Mary J. Blige Is, Frankly, Quite a Good Tipper

David Patrick Columbia and Donald Trump will judge the plaid fashions at Sean Connery’s Dressed to Kilt fashion show to benefit Friends of Scotland at M2 tonight. Scots strutting down the catwalk will include Katrina Bowden, Maggie Rizer, and Andie MacDowell. After Fast Money’s Dylan Ratigan called it quits on CNBC on Friday, he might be headed for ABC. Ian Schrager is feeling the weight of the recession too. He’s offering guests 50 percent off every other night spent at the swanky Gramercy Park Hotel. It’s okay, though, he’ll make up for it with Rose Bar’s pricey cocktail menu. Speaking of which, Chace Crawford just had a business meeting there. Mary J. Blige downed tequila while dancing to her own songs at M2, then tipped her waitress $500.

Mariah Carey and Nick Cannon partied at Cabana One Lounge in Coconut Grove during the Winter Music Conference in Miami. Cannon later played Carey’s songs while D.J.-ing at Ron Berkowitz’s rooftop club — that is, until Carey grabbed the mike and sang Fantasy. Fergie rocked out at the Fountainebleu for her birthday. New father Ricky Martin shook his bon bon till 3 a.m. at Mansion in South Beach, after escaping a hysterical fan. A little socialite scuffle also ensued at the Fountainebleu when Paris Hilton asked D.J. Steve Angello to put on some Madonna or the Black Eyed Peas. When he declined, a brawl broke out with the party princess herself, leaving her boyfriend Doug Reinhardt with a bloody lip. Hilton, naturally, came out unscathed.

Brody Jenner sidekick and Hollywood Z-lister Frankie Delgado has been buddy-buddy with Rihanna, chatting up the press about her just to see his own name in print. Rocker Tommy Lee was getting cozy with former MTV reality-show contestant Natasha Komis (over twenty years his junior) backstage at the Mötley Crüe concert. And speaking of youngsters, working women are heading back to the office sooner than ever after having babies. Jenna Jameson partied at West Hollywood’s gay hot spot, the Abbey, just six days after giving birth to twins.

John Mayer says he hates Twitter. Star Jones started a “positivity” blog. Save the Children is accusing Madonna of conducting a “puppy parade,” flaunting her plans to adopt 3-year-old Malawian Mercy James. Soulja Boy was sad that Rihanna and Chris Brown were no-shows at Nickelodeon’s Kids’ Choice Awards even though both were nominated. And Nora Ephron might feel bad about her neck, but she’s jealous of Michelle Obama’s arms.

In uptown news, Blake Lively and Leighton Meester needed crew members to help them out of their Über-high heels while filming the Gossip Girl season finale at Rouge Tomate. Julia Roberts bought daughter Hazel a Lilly Pulitzer headband at the preppy Madison Avenue boutique. Bernie Madoff has had at least one affair during his 50-year marriage to Ruth.
