Party All The Time

And now ... YG gets a lesson in Hollywood nightclub politics, and that lesson is: A bunch of penises will get you nowhere, son!

The rapper showed up at 1 OAK on the Sunset Strip Thursday night with a whole crew of dudes, and we got this video of their repeated efforts to get in the club.

They tried the back door, then the front door. YG even got a VIP host on his side, trying to get him in the club ... but still got dissed by the mountainous bouncer who declared, "There's too many dudes."

Mind you, Justin Bieber and Wiz Khalifa had no problems getting into 1 OAK the same night, but as the bouncer put it -- "Wiz comes with girls!"

The more you know.

Justin Bieber got all kinds of crazy celebrating his album release Thursday night -- so crazy, he downed a whole bottle ... of beer.

Check out this video of Justin leaving the Man Cave Sports Bar -- first, he responded to country star John Rich's rant against him. But then some fans ask him how much he had to drink in the bar.

Bieber was straight up about his boozing ... if you can call it that.

Earlier this week, Justin was partying at 1 OAK for French Montana's birthday and we got some video of him having just ONE bottle again. Of course, that one was Ciroc, but he only sipped.

Pamela Anderson is partying in the sex club capital of the world, which makes sense now that she's cured of Hep C.

Pam was partying at Bricks nightclub in Berlin Thursday night after the Bambi Awards.

Pam has reason to celebrate ... she just revealed she's "cured" of Hep C with the help of a very expensive, experimental drug.

5:05 PM PT -- A spokesperson for the U.S. Coast Guard tells TMZ they received a call for a woman who went overboard at 7 PM EST ... the boat is currently 22 miles off the coast of Cuba and the USCG has an airplane and several boats on the way. We're told they're also reviewing footage from the incident.

A woman has gone overboard from a cruise ship loaded up with EDM acts like Skrillex, G-Eazy, Diplo and Major Lazer -- and their fans.

We're told the woman fell from the Mad Decent Boat Party, which took off Wednesday from Miami bound for Cozumel. Our source says 3 rescue boats have been deployed to start searching for the victim somewhere in the Caribbean.

Passengers just received a message from the captain saying no one has been found yet.

It's unclear if the woman jumped or fell.

The Weeknd and Ed Sheeran don't just spare change for homeless vets in the street ... they drop bills, as one lucky guy found out.

The singers happened to leave Leo DiCaprio's birthday party Wednesday night in NYC right after each other, and both were approached by a guy who said he's an ex-soldier just looking for a warm meal.

The fact it was Veteran's Day probably helped his cause ... plus, it's been a really good year for Ed and Weeknd. But ultimately, we think it was the guy's hustle that scored him some cash.

Floyd Mayweather hit the same Hollywood club as T.I. and Tiny Wednesday night -- but it doesn't seem the hatchet is buried all the way.

The three have a pretty nasty past -- which culminated in a BRAWL in Vegas last year when Floyd publicly claimed to be banging T.I.'s wife.

They seemed to have squashed the beef earlier this year ... but last night, it was pretty obvious there's still tension.

Mayweather arrived at Warwick first ... followed by T.I.

Tiny arrived a short time later by herself ... but only stayed for 3 MINUTES before she and T.I. bolted from the club.

Justin Bieber is still in the FRIEND ZONE when it comes to Josie Canseco -- with the bikini model telling TMZ Sports there was NO HUMPING when they left the club together Tuesday night ... 'cause she's already got a BF.

Leo DiCaprio celebrated his 41st birthday at Marquee nightclub in NYC, surrounded by a sea of celebs.

Check it out ... Leo walks in, followed by Bella Hadid and The Weeknd ... which is interesting because of the buzz that she dumped him. Also on hand ... Busta Rhymes, Ed Sheeran and Tyson Beckford.

Pepa was the victim of a setup for her 51st birthday -- her friends and family organized a baller surprise party to kick off a month-long celebration.

Pepa told us her husband, Gurps Singh Rai, was the mastermind behind the whole thing. He pretended they were going out for a quiet dinner, but ended up at SIXTY LES in NYC with about 300 people.

We're told guests feasted on a soul food themed spread -- mac & cheese, chicken wings, cupcakes and cake. This was just the start. Pep says she and Gurps are vacationing in Dubai later this month.

Ed Sheeran managed to squeeze the entire college experience into one awesome and boozy night.

Sheeran -- who dropped out of school at 16 -- was spotted all over the college town of Chapel Hill, NC Tuesday night. He was joined by rumored GF, Cherry Seaborn, who attends Duke.

Check out the video ... Ed's adorably giddy over learning (and eventually mastering) the art of beer pong at a Duke party.

French Montana celebrated his bday Tuesday night in the best way possible ... with all of his super famous friends.

French, who turned 31 on Monday, was at 1 OAK in L.A. joined by the likes of Justin Bieber, Amber Rose, Meek Mill, Wiz Khalifa, Keyshia Cole and Chris Brown.

We don't know if there was cake, but we hope they kept it French when it came time to sing "Happy Birthday" ... "Haaaaaaaaaaah!!"

Sooo ... Justin Bieber left a Hollywood nightclub with a smokin' hot model Tuesday night -- and our sources tell us the mystery woman is Jose Canseco's daughter Josie.

Wiz Khalifa and Amber Rose threw the "L" word around a lot when they reunited on the Sunset Strip ... and it sure looked like someone was catching feelings again.

The exes chopped it up outside 1 OAK after French Montana's birthday party, and anyone standing nearby might have thought the old spark was coming back. Especially when Amber started banging on Wiz's window, screaming about a chick in the SUV with him.

But the drama ended with a laugh, and while both talked to us about their "love" ... they also squashed any "getting back together" rumors. Amber was passionate about someone else -- a chick who yelled, "What a slut!"

Amber's response is awesome.

Justin Bieber offered up a clue on why he went off the rails in Europe ... he's just really tired.

Justin showed up with French Montana at 1 OAK Tuesday to celebrate French's birthday. People inside the party tell us Justin was chill ... his drink of choice was Hennessy straight.

Amber Rose revisited her humble beginnings Monday night, and shared her wealth with the strippers at Ace of Diamonds.

Amber, an ex-stripper herself, if you didn't know ... put on her best mesh dress to host at the popular L.A. gentlemen's club. She kept the ladies happy, tossing fistfuls of cash all night -- pausing only for twerk breaks and ass grabs.

Best of all -- the shots of Amber giving special attention to a stripper who looked EXACTLY like her!

The chick's got a type.

Justin Bieber's gonna be your ultimate wingman -- hooking you up with a ride, hitting the club and doing shots with you ... if you're really lucky.

Bieber’s teaming up with Lyft for “Bieber Mode” -- a week-long feature where he might show up in a requested car anywhere in the country, starting Thursday.

We've learned, Justin warmed up for his Lyft duties last month with a pick-up in Hermosa Beach, CA.

Bieber chatted up the passengers, one of whom turned out to be a local DJ. Justin kept the party going by showing up at the guy's gig later that night. He even got on the mic, and performed an impromptu rendition of "What Do You Mean?" ... in between shots of tequila.

Definitely beats a cab.
