A-Rod and Mariano Rivera seem to be putting aside their Red Sox rivalries to attend David Ortiz's celebrity golf tournament in the Dominican Republic. Or they just want to slam him on the golf course. Rodriguez also gave Kate Hudson a white-gold Louis Vuitton ring, but he says it's only to thank her for her in-stands support. Rihanna is moving on from Chris Brown with the help of 90210's Tristan Wilds, who attended her industry-only party in L.A. over the weekend. Wilds is also trying to launch a music career, but that probably has nothing to do with his interest in RiRi. Despite reports that Wall Street 2 co-stars Shia LaBeouf and Carey Mulligan are no longer dating, the couple sneaked in several unstaged on-set kisses on Monday. A sweat-drenched Jonah Hill cooled off outside Bowery Electric after "dancing like a madman." A bouncer at the New Moon premiere wouldn't let Kellan Lutz into the after-party. And Bijou Phillips was too embarrassed by her half-sister Mackenzie's incest revelations to attend the premiere of her own film Made for Each Other, in which she has "many sex scenes" with the brother of her real-life fiancé, Danny Masterson. A newly divorced Avril Lavigne got cozy with Wilmer Valderamma at L.A.'s Wonderland on Saturday.

Though Charlie Gibson says he and Diane Sawyer "developed a strong mutual bond" during their seven years of working together, insiders claim he's "always given Diane the stink eye" and he wants George Stephanopoulos to be his This Week successor. Senator Chuck Schumer pushed his cart through Brooklyn's Costco, and Nancy Pelosi breakfasted at Tarallucci e Vino. While en route to dinner with Ricky Martin and Bulgari CEO Francesco Trapani, Gloria Estefan lost her $220,000 diamond bracelet. Fortunately, Emilio found and fetched it. Before Sex and the City 2 hits theaters in May, Candace Bushnell is releasing The Carrie Diaries, a young-adult novel set during Carrie's high-school years. 50 Cent had his arm tattoos removed because he doesn't like having to show up to acting jobs four hours early to get them covered with makeup.

Johnny Depp, Danny DeVito, Patti Smith, and Helena Bonham Carter vodka-toasted Tim Burton at the Russian Tea Room to celebrate the opening of his MoMA exhibit. Cindy Crawford's alleged blackmailer turned himself in to German police. Jane Fonda, Forest Whitaker, and Christian Slater were honored in Dusseldorf. J.Lo's ex says she's having him followed, and he's received death threats ever since he tried to sell a book and racy home movies of her. Ben Affleck and Blake Lively took a trip to Mohegan Sun to shoot a casino scene for The Town. And while running errands with his daughter, Hugh Jackman stopped to chat with a woman selling Obama condoms.
