Miley Cyrus & Liam Hemsworth

Miley Cyrus posted an interesting 25th birthday pic ... with the hashtag, VeganTurkeyBaby.

She loves screwing with the media, so don't read too much into this, but she knew what she was doing for sure when she wrote the caption.

And check out the rhinestone chain Liam got her for her B-day.

Gotta say ... we know she started out young, but it feels like we've been following Miley for 3 decades. She was 11 when she first starred in "Hannah Montana."

Regardless ... Happy Birthday!!!

Miley Cyrus broke down crying in Vegas yesterday ... while she performed a song rumored to be about her break up with Liam Hemsworth.

Miley twerked it up on stage at the iHeartRadio Music Festival -- but the tears started flowing hard once she began singing "Wrecking Ball."

As we previously reported -- the couple has called it quits ... and Liam has gotten tight with telenovela actress Eiza Gonzales -- who BTW is crazy hot.

Despite the cry-fest ... Miley cleaned up for her second performance of the night.

And wore this.

Hours after "officially" announcing his split from Miley Cyrus, Liam Hemsworth hit the town with ANOTHER woman last night -- his mother.

Liam, along with breeder of blue-eyed, Australian demigods Leonie Hemsworth, was spotted leaving the famous Chateau Marmont on the Sunset Strip together.

Earlier in the day, reps for Miley and Liam announced their engagement is off ... but offered few details as to what caused the split.

Liam didn't seem too crushed over the breakup this weekend, when he was spittin' game to Mexican singer/actress/dimepiece Eiza González in a Vegas nightclub.

As for Liam's mom -- think she's upset about the split from Miley? Or relieved?

Discuss ...

Miley Cyrus and Liam Hemsworth are DUNZO -- 'cause there was no going back once Miley unfollowed her ex-fiancé on Twitter.

The hot chick with Liam in Vegas didn't help the sitch either ... we're guessing.

Call him Dennis Rodman, 'cause Liam Hemsworth was rebounding like a CHAMP in Vegas last night ... spittin' some serious game to a smokin' hot chick -- and from the looks of things, it worked.

Just one day before reps "officially" announced the demise of his engagement to Miley Cyrus, Liam and 5 of his friends hit up XS Nightclub ... where he ran into 23-year-old Eiza González.

FYI -- Eiza happens to be a singer/actress (seems like someone's got a type).

They drank ... he smoked ... they flirted ... they were thisclose ... and people in the club said they never left each other's side before leaving the joint together at 2 am.

Muy bien.

It's one thing not to be seen together, but when you unfollow someone on Twitter it's pretty clear ... Miley Cyrus and Liam Hemsworth are dunzo.

Miley 86'd Liam from the social media site yesterday. He's still following her, but it takes 2 to follow in a fiance sort of way.

Miley and Liam have barely been seen together in the last few months, and when they were they looked like they were in pain.

Was Liam pissed at Miley's twerking video? Was he upset with what she was wearing at the VMAs? Was he infuriated at what she did to Robin Thicke?

So much to be pissed over.

1:40 PM PT -- Adding more fuel to the fire ... Liam was spotted out last night in Vegas at the Mayweather fight sitting near "Twilight" star Ashley Greene.

Justin Bieber might be getting handfuls of Miley Cyrus' Montantas -- which would totally ruin the sex appeal points she just earned with that insane twerking video ... almost.

Yep ... it's that good.

Miley Cyrus says it's "impossible" that she's more than friends with Justin Bieber ... despite the public flirting ... 'cause she's currently engaged to someone else.

Miley called in to Hot 99.5 in D.C. this morning ... and actually responded when the DJ asked if the photos on TMZ showing Miley and Bieber flirting in public this weekend prove they're "more than friends."

Her response: "I'm ENGAGED!" she said, chuckling. "I'm engaged. That is impossible."

It's an interesting statement for two reasons -- first, it clears up the rumors that she broke things off with Liam Hemsworth.

Second, when it came to being more than friends with Justin ... her answer isn't exactly a strong "no."

Miley was also asked about Amanda Bynes -- and she says some interesting stuff.

Give it a listen.

Miley Cyrus is blazin' a trail for millions of young women in America ... it's actually a trail of smoke that makes you really hazy and giggly.

She's not hiding it anymore ... no more, "It's not marijuana, it's Salvia." The smoke sesh went down Sunday night at Greystone Manor in Hollywood.

Greystone is turning into the go-to ganja joint ... Rihanna was toking a fat one a week earlier.

Liam and Miley have a lot in common ... except her hunger game ends with a bag of Cheetos.

Disney princess turned wannabe hipster badass, Miley Cyrus took time out from twerking to flash her engagement ring while taking her Urban Outfitters approved beanie and black American Apparel-ish negligee for a bra-free stroll in Hollywood on Wednesday.

Forget looking at photos trying to spot a ring or trying to decipher a cryptic tweet ... here's Liam Hemsworth spotted yesterday outside the Los Angeles home of his fiancée, Miley Cyrus.

Despite rumors of infidelity, hardly being seen together, and Miley's on-again/off-again engagement ring ... it seems this young couple is still going strong.

Liam Hemsworth got back to the U.S. just in time to see an awesome video of Miley Cyrus twerkin' her ass off! If they really are broken up -- this looks like the best reason for them to get back together.

First Miley Cyrus' engagement ring returned ... now Liam Hemsworth is back -- but whether their engagement is back on is the big question, and we posed it directly to Liam.

Hemsworth arrived at LAX last night after a THREE WEEK trip to Australia and the Philippines ... sans Miley, and on the heels of rumors he and January Jones had a fling.

We asked Liam about everything from Miley's disappearing and reappearing diamond ring ... January (the month and the chick) ... and even the quality of gnar Down Under.

Miley Cyrus sent a message to her fans -- and possibly her MIA fiancé Liam Hemsworth -- by showing her enormous engagement ring is back where it hasn't been for a while ... on her hand.

Miley posted a photo of herself -- in a unicorn onesie, by the way -- prominently featuring her left hand weighted down by her diamond rock.

As everyone's heard by now ... Miley and Liam have allegedly broken off their engagement. He's been with family in Australia -- and she's been spotted all over town sans ring.
