Wednesday gossip roundup: Is Snooki pregnant with Jionni’s baby?

Jennifer Garner gave birth to a son Tuesday in Santa Monica, Calif., according to People magazine. It’s the third child and first boy for Garner and husband Ben Affleck, who also have daughters Violet, 6, and Seraphina, 3. Garner previously said that they knew the gender of the baby ahead of time but weren’t sharing that information. “It would be so weird to have a boy,” she told Ellen DeGeneres during an interview last year.

While she recently denied it, sources tell Page Six that Nicole “Snooki” Polizzi is indeed three months pregnant with boyfriend Jionni LaValle’s baby. The “Jersey Shore” is reportedly looking to make the most of the announcement — and has even brokered a deal for a cover story with Us Weekly, according to the source, who says Snooki is looking to use her pregnancy to become “the next Kourtney Kardashian.” But reps at MTV aren’t as excited, since Snooki is currently filming a “Jersey Shore” spin-off chronicling her hard-partying lifestyle. “MTV went into crisis mode after they found out,” the source says. “They’re trying to hide it because it would greatly affect the creative direction of the show. ”

Lindsay Lohan is mounting her comeback, starting with a stint hosting “Saturday Night Live” this week, and she knows there’s a lot at stake. “I will not let anyone down, especially myself,” she says in an interview with the “Today” show, starkly contrasting her last visit to the show, during which she denied having any problems at all. “I wasn’t as comfortable with myself then. I think it was a fear factor that I had about what was really going on. And, you know, I had to get that wake up call.”

Jennifer Lopez had more than one awkward moment the night of the Oscars, as the singer ran into ex-boyfriend Sean “Diddy” Combs at the Vanity Fair after-party, according to Us Weekly. Lopez, who attended the bash with 24-year-old boyfriend Casper Smart, reportedly headed straight to Combs when she spotted him and seemed “friendly” during their chat. A witness overheard Lopez apologizing for not returning Combs’ calls and text messages. “It was weird,” the source says.

Plans are reportedly already underway for a movie about Whitney Houston’s life, according to the Daily Mail. Producer Clive Davis is behind the project, and while Jennifer Hudson, Vivica Fox and Jordin Sparks are reportedly on the list for the lead role, Davis is said to have his eye on Rihanna to play Houston. And lest it seem like Davis is trying to cash in on his friend’s death, the film was reportedly already being developed before Houston passed away last month. “Whitney knew about the project and was excited to see where it would lead,” a source says.

After a brief stay at the Betty Ford Center, Gerard Butler was out and about, hitting up the Vanity Fair Oscar party on Sunday. “I probably shouldn’t talk about it to you, but I feel pretty good,” Butler told Page Six. “I don’t think I look too bad.” According to TMZ, Butler headed to rehab to address a prescription drug dependency before it became a full-blown problem.
