Chris Brown & Rihanna

Drake claims Chris Brown refuses to bury the hatchet in their long-running and violent feud ... and what's more -- Drake says, "I get a feeling it could end really badly."

Drake had finally broken his silence about his war with Brown to GQ ... even talking about the bloody bar fight that went down inside W.i.P. in NYC last June.

“I don’t want my name to be synonymous with that guy’s name," Drake says ... "I really don’t. I wish we could sit down, just like you and me are right now, and talk it out man-to-man."

He continues ... "But that’s not going to happen. I’m not confrontational, but if someone challenges, I’m not going to back down."

Drake says he's "embarrassed" by the media coverage ... saying, "Two rappers fighting over the woman. He’s not even a rapper, but still, it’s the last way you want your name out there."

And then comes Drake's dark prediction ... saying the feud "distracts from the music. But he’s made me the enemy, and that’s the way it’s gonna stay, I guess."

"If I think about it too much, I feel it wrapping around my foot, like I get a feeling it could end really badly.”

Call her crazy ... but Karrueche Tran and Chris Brown are full-on LIVING TOGETHER ... TMZ has learned.

Sources close to the couple tell TMZ ... they hooked up days before his 24th birthday earlier this month and she's been staying at Chris' Hollywood Hills home ever since.

Though she's keeping her own apartment -- smart -- she's already moved most of her clothes and other personal belongings to his pad.

And it's not like they've been secretive ... they've been spotted everywhere lately, hitting up the Billboard Awards afterparty and even rear-ending a Mercedes together.

Karrueche's one persistent scorned lover -- when Chris first dumped her back in October for Rihanna -- she vowed to win him back, as TMZ first reported.

So where does this leave Rihanna? RiRi and Breezy officially called it quits a few weeks ago ... but they've ALWAYS had an on-again, off-again relationship ... and Chris has made it no secret -- he loves 'em both.

Dear Rihanna,
Please provide Chris Brown frequent Instagram reminders of what he's no longer tapping -- such as your barely covered ass -- since he was stupid enough to break up with you.
Love,
The Internet (and everyone who uses it)

Rihanna just gave ex-boyfriend Chris Brown a little taste of what he's missing ... her perfectly sculpted ass.

RiRi just posted an extreme close-up shot of her nearly bare derriere in shorts that are so tiny, her THONG is hanging out of 'em.

Rihanna added a caption saying the pic was from the set of her new music video ... but we think it's pretty obvious the photo was for an audience of 1 -- Chris ... who was recently spotted out with his other sometimes-GF Karrueche Tran (who definitely doesn't have an ass like Ri).

Think he's regretting the breakup yet?

With Rihanna in New York City on her Diamonds World Tour, Chris Brown celebrated his birthday at Emerson nightclub in Hollywood ... with ex Karrueche Tran in attendance.

We're told Karrueche -- Chris' other on-again/off-again girlfriend -- was invited by Chris himself to the party (thrown by ZING Vodka and Black Pyramid) to celebrate Chris turning 24. Our sources say the two still talk often and hang out, and that she still cares about Chris very much.

Here's to hoping some combination of these crazy kids can make it work.

Chris Brown might despise Drake with a passion, but even CB can't resist dancing when one of his songs comes on at the club.

Brown and Drake have been beefing for a while now -- peaking last June with a massive club fight, reportedly over Rihanna.

CB was hosting a party at Stage 48 in NYC earlier this month and apparently the DJ had no fear at all ... and played a Drake song, "Started From the Bottom." Rather than react (how do we say this nicely?) poorly ... CB simply got down like it was his favorite jam in the world.

Chris Brown's own father has the same feelings as most of America does when it comes to his son dating Rihanna -- they should have NEVER gotten back together.

In an interview with the New York Daily News, Clinton Brown said that while he understand CB's attraction to RiRi, they are better off on their own. He told the paper, "I personally really didn’t want him and Rihanna back together."

The elder Brown, who split from CB's mom when he was 6, thinks the on-again/off-again couple does not have the proper balance to maintain a good relationship, explaining, "You have to have someone who is spontaneous and whimsical but you also have to have someone who is grounded and logical."

Chris Brown has a new toy and it ain't Rihanna ... it's a ridiculous Hot Wheels inspired Lamborghini.

Trying to go unnoticed in the flashiest car in the world, Breezy took his new whip out for a spin to Supperclub in Hollywood last night.

Rihanna came out of a medical building in Bev Hills Tuesday ... and said she's doing a lot better, but it's done nothing to stop the pregnancy talk.

Rihanna has cancelled 4 concert dates on her Diamonds World Tour ... which kicked off on March 8.

Sources connected to the singer told TMZ in early March she was suffering from a throat infection. Thing is ... it's been more than a month now and there are clearly still issues.

Because the info coming from Rihanna's camp has been sketchy ... there have been a slew of tabloid stories speculating that she's pregnant.

Drake is holding nothing back about his feelings toward Chris Brown ... ripping CB over his music and the way he treats Rihanna -- and doing it in a very public forum.

Drake sat down with Elliott Wilson on his "Keep It Thoro" Internet radio show last night, and absolutely tore Chris a new one ... saying, "His insecurities are the fact that I make better music than him, that I'm more popping than him and that at one point in life the woman that he loves fell into my lap."

He added, "I did what a real n***a would do and treated her with respect."

Damn.

Drake did leave open a slight chance for reconciliation, saying, "We have an issue and it's either gonna drag out or maybe in ten years we'll laugh about it over drinks. Just let us solve that s**t."

Rihanna has once again taken back Chris Brown ... at least for now ... 'cause the two were rollin' around L.A. together in the same expensive car yesterday.

As we previously reported, the two have been breaking up and getting back together more often than Van Halen ... but yesterday, it seems they were "back on" for the day.

In fact, Rihanna even tweeted a pic of the twosome together looking as coupley as ever.

Think they'll make it through the week?

Drake started the blowout NYC nightclub brawl last summer with Chris Brown ... by sending Brown a handwritten note that read "I'm f***ing the love of your life" -- this according to Chris Brown's bodyguard.

According to the lawsuit, obtained by the NY Daily News, Patrick Strickland -- whose head was badly bloodied during the flying bottle attacks -- is suing Drake and W.i.P. nightclub, where the brawl took place last June.

Strickland says Drake's note -- a clear reference to Rihanna -- started a verbal altercation, which then led to the all-out melee in which several people were badly injured ... including Strickland and several other clubgoers.

According to Strickland, the club is also responsible for over-serving Dreezy -- and seating him way too close to Chris ... in light of their public beef over RiRi.

Rihanna's gone up in smoke after calling it quits with Chris Brown ... ripping a fat blunt inside a Hollywood nightclub early Monday morning ... and TMZ has the pic.

Sources inside Greystone Manor nightclub tell us, Rihanna arrived around 1am with her assistant and security guard ... and pretty much kept to herself. She left an hour or so later.

As we reported, Rihanna and Chris Brown are officially broken up ... but our sources say it's nothing new for the on-again-off-again couple. We're told they'll be back together in no time.

You might call it a chronic problem.

The mystery blonde who's been accused of destroying Chris Brown's relationship with Rihanna isn't exactly a threat ... because she says she prefers vanilla over chocolate.

22-year-old Keisha Kimball -- a waitress at L.A.'s Playhouse nightclub -- was photographed holding CB's hand last Saturday inside the club ... and now she's being blamed for Chris and Rihanna breaking up.

But Keisha tells TMZ, “I am always Chris’ waitress. I know him and am friends with his friends. Nothing has ever happened. I just work there. In the photos, he was handing me a bottle to drink out of. Of course people are going to twist it another way. I don’t go for black guys."

Keisha -- who says she's not racist ... it's just a dating preference -- adds, "Whatever is going on between Rihanna and Chris Brown is between them. I’m not trying to be a home wrecker."

And get this ... Keisha says CB is normally a great tipper, but last weekend he stiffed her ... in the gratuity department of course.

As for the CB/Rihanna breakup rumors ... our sources say they're true ... but it's nothing out of the ordinary for the on-again-off-again couple.

It took Chris Brown 23 years but he's finally done it -- he's learned that hitting women is a bad thing!

CB sat down with Matt Lauer on "Today" this morning and actually opened up about his relationship with Rihanna, rather than throw a chair through a window when asked about it.

"As far as me and her are concerned," Brown said ... "She knows my heart and I know her heart. I'm not really focused on the negative, everything about it is positive for me. I did my 52 weeks of counseling and learned that it was absolutely wrong."

So that's a 23-year-old man ... having to learn that beating the living crap out of a woman ... is wrong.

Chris Brown is backing off last week's proclamation that he is sole and rightful owner of Rihanna's lady parts ... telling TMZ, "It's a song ... it's a song ... that's all it is."

Brown was leaving Lure nightclub in L.A. this weekend when we brought up the statement he made at the Emerson Theater last week ... when he gave the crowd a quick lesson about how to talk to women.

"You GOTTA say that one thing to her," Brown said ... "Don't make me have to tell you again, that's my p***y baby! ... so you better not give it away!"

But on his way out of Lure, Brown was playing it off as if it were only a joke ... so we joked back.

Chris laughed ... it was kinda funny. Check out the clip.
