Party All The Time

Toronto's crack-smoking Mayor Rob Ford is never done campaigning -- not only did he throw down big money to party with hot chicks in Hollywood after the Oscars last night ... he actually handed out Ford-themed commemorative magnets to his female admirers.

Actress/socialite Meredith Thomas tells TMZ, she and a friend ran into Ford at the post-Oscars bash at the W Hollywood -- where they found him chilling in his own private cabana by the pool.

Thomas says she asked Ford for a photo and he obliged -- then handed her and her friend a Rob Ford Mayor magnet and a business card. Thomas says Rob asked her to stick around, but she declined.

As for Ford's poolside cabana -- it didn't come cheap. We're told the average price for cabanas Sunday night was $2,500 a pop, including booze.

Magnets attract ... but they also repel.

12:48 PM PT -- We just got the FULL birthday wish video ... Lil Wayne, Nicki Minaj, Mack Maine, Bow Wow, and DJ Khaled are in it too. Pretty cool.

Justin Bieber now does BIRTHDAYS -- at least for the filthy rich daughters of millionaire rap executives -- and we got video proof ... the Biebs singing for Birdman's little girl at her over-the-top sweet sixteen this weekend.

Bria Williams celebrated the big 1-6 at The Bath Club in Miami Beach Saturday night -- a Paris-themed bash replete with a Bugatti'd out arrival, a "glitter" carpet entrance, a giant cake ... and her big present, a matte black Mercedes G-Class.

But the real highlight -- Bieber sent her a "happy birthday" video ... which was played in the middle of the party.

It's a nice gesture ... but don't count on Bieber sending you one if you're not worth at least $100 million.

Justin Bieber just can't quit Selena Gomez ... he lustfully posted pics of his ex-GF at an Oscar party ... even though he's 2000 miles away in Atlanta

The pic shows Gomez at the Vanity Fair party last night in West Hollywood -- where she showed up in a gold, beaded Pucci gown -- with the caption, "Most elegant princess in the world."

Could be Justin's just jonesing for his old life in L.A. -- which once included Selena?

The feeling may not be mutual ... Gomez -- who went to rehab in Jan. partly over her Bieber addiction -- has kept her distance from Justin and his new crew.

Oksana Grigorieva forgot she's bankrupt and no longer dating a famous dude ... because Sunday night in Hollywood she tried getting into the post-Oscar Vanity Fair party -- and got SHUT DOWN!!

Mel Gibson's ex and some friends attempted to enter the party but none of them were on the list and the doorman wasn't having it ... so they took the walk of shame back to their ride.

Maybe they were worried she'd start recording the celebrity action inside.

Sorry Oksana, better start hunting for a new sugar daddy somewhere else.

The Governors Ball better stock up on munchies ... because local weed delivery services are BLOWING UP with orders this weekend from celebs looking to get baked.

According to our ganja sources ... a ton of delivery pot shops had to hire more drivers for Sunday to keep up with the insane amount of orders being placed all weekend by celebs in town for the awards show.

One company told us portable vaporizers are huge with celebs this year ... and they've already sold around 40% more bud than usual. We're told the top selling strain is called Dream Queen.

The night is still young.

Citizens of Toronto, fear not ... even though your sometimes crack-smoking mayor just touched down in Hollywood to apparently hit up the Oscars -- and after his recent trip to Mardi Gras -- he claims the city is still in good hands.

Rob Ford made his way through a media storm of cameras Saturday night at LAX (video to follow) ... telling our photog he's running political biz from the road -- and even plans to run for office again later this year.

"Crack Mayor" told the Toronto Sun early Saturday morning he was flying to L.A. to attend the Academy Awards ... but when he got to baggage claim Jimmy Kimmel was waiting as his driver ... so this was clearly all for his late night show.

Watch the clip ... see which d-bag Canuck we'd get in a trade with Canada -- him or Bieber.

George Lopez says revenge is a dish best served drunk ... or at least something like that.

Lopez took the stage at Caesars Windsor Friday night in Canada -- just one day after getting arrested for public intoxication at the same hotel -- and candidly spoke about his arrest.

The comedian opened the show saying, "I just did in Windsor, what Justin Bieber does in America" ... then told the audience he took 52 shots before passing out in the bar of the hotel the night before.

One thing George makes very clear throughout his gig ... the arrest didn't cramp his style.

Eh, take that Canada!

Justin Bieber -- no longer a teenager -- and to celebrate that he blew out candles on a cake that looks like it was made for child.

Bieber -- or according to the cake, Bizzle -- turned 20 Saturday morning ... and he wasted no time kicking off the celebration.

WHAAAT! Things got way too hot for Lil Jon in Vegas last weekend -- some hot blonde chick twerked her ass off at his table ... and the rapper decided she needed to chill ... with a glass full of ICE CUBES.

The video was shot Sunday night inside XS Nightclub -- it's pretty wild ... and Lil Jon obviously knows talent when he sees it ... because the girl in the clip has serious skills.

2:55 PM PT -- George just gave us the greatest statement ever ... “Tied one on last night. Not feeling great this morning. I was trying to sleep it off, unfortunately, it was on the casino floor.”

George Lopez had one too many last night at a Canada casino -- law enforcement tells TMZ, the comedian was arrested for public intoxication after passing out on the casino floor.

Law enforcement sources tell us Caesars Windsor security alerted police to the Lopez situation -- presumably after they found him on the floor -- and officers subsequently arrested him
inside the casino bar at Caesars Windsor.

No charges are being filed against Lopez -- we're told he was pretty much dumped in a drunk tank to let him sober up.

Lopez had performed at the casino just prior to his arrest and is scheduled to perform again tonight.

Lopez has been released and we're told he will perform tonight.

Michael Strahan's fiancee proved he's a lucky man Wednesday night at a karaoke bar in Malibu -- by showing off her serious ass-shaking skills and putting young hotties to shame.

Nicole Murphy popped her booty to "Pony" by Ginuwine at Cafe Habana with co-stars Shamika Lawrence and Mayte Garcia ... and the other "Hollywood Exes" were clearly not in her league.

The trio attempted to sing "Hold On" by En Vogue as well (video below) ... but there's a lot less butt shaking.

Our apologies.

Justin Bieber is going harder than ever on sizzurp and weed since living in Atlanta ... multiple friends involved in his life tell TMZ.

TMZ broke the story ... Justin has had an alarming problem with sizzurp for well over a year, and he's been a big fan of weed for a long time. But since moving to Atlanta, we're told he's "constantly high" ... rarely leaving the house. As one source said, "Drinking more lean, smoking more weed than ever."

When Justin lived in L.A. he had a schedule set up by people connected to his business. Since moving to Atlanta, he has no schedule and no rules.

Some of the people in Bieber's life that have confronted him about his drug use have been pushed away since Bieber made his move. And we're told -- one by one -- Bieber is removing people he says have "ratted" him out over his drug use.

Justin does spend a fair amount of time in the studio in Atlanta ... working on hip hop ... but we're told rarely is he sober during those sessions. And the thing is ... that's part of the rap game.

Rihanna and Drake got it on last night in Paris ... in front of 17,000 people ... grinding on stage to their duet "Take Care" -- and it's all on video.

As we reported, Drake and Rihanna have been inseparable in Paris since Drake flew into town this weekend for his tour, getting dinner, hanging out at nightclubs ... even crashing together at the same hotel.

And the chemistry on stage last night is undeniable -- take a close look at Rihanna's face.

There's no way she's acting either ... because she sucks at that.

The fat lady hasn't sung in Robin Thicke's marriage ... at least according to him, because he has had time to think and he's now determined to win Paula Patton back.

TMZ broke the story ... Paula called Robin on Friday to tell him she wanted a divorce ... and Robin jumped on a plane and flew to Canada and tried in vain to convince her to change her mind.

Sources connected with the singer tell TMZ ... Robin desperately wants to save his marriage. We're told he's resuming his tour on Thursday where he's performing in Washington D.C., but he will NOT go out on the town -- something he liked doing in the past.

We're told he wants to convince Paula he can change and be a good husband. The surreptitious ass-grabbing is a thing of the past.

Sources also tell us ... Robin is really concerned about their son. He does not want him raised in 2 separate homes.

The couple released a statement saying they have separated ... but our sources made it clear ... she wants a divorce.

This is WhatsApp co-founder Jan Koum in Spain with his girlfriend ... celebrating Facebook's $19 BILLION purchase of his company, and his 38th birthday.
