Katie Holmes made her official New York Fashion Week debut, as Holmes & Yang — the fashion line she started with stylist Jeanne Yang — showed off its spring line for the first time at the big event. Holmes was very hands-on with the models and reportedly no celebrities were in attendance. “They wanted to keep it intimate,” an unnamed insider tells the New York Daily News. A People editor told the Associated Press that the 14 looks the former Mrs. Tom Cruise showed off were “very clean but with a cool factor.” (New York Daily News; Associated Press)

There’s going to be a new Barack Obama on “Saturday Night Live” this season. Jay Pharoah will take over the presidential impersonation duties previously assumed by Fred Armisen. Lorne Michaels tells the New York Times, “I just thought it might be time to shake it up.” (New York Times)

In what sounds like something that might happen in an episode of ”The Newsroom,” Alison Pill, star of “The Newsroom,” accidentally tweeted a topless photo of herself Wednesday, then quickly deleted it and sheepishly apologized. She gained 2,000 new followers as a result. (L.A. Times)

AEG Live — the concert promotions company that was behind Michael Jackson's “This is It” tour — has filed a request to obtain drafts of a memoir Jermaine Jackson was writing prior to his brother’s death. AEG attorneys have defended the request, which Jermaine’s Jackson’s lawyers have objected to, because they say the manuscript contains evidence of Jackson’s long-standing prescription drug issues. Katherine Jackson is suing AEG, accusing the company of not adequately supervising Conrad Murray’s treatment of her son while preparing for his comeback tour. The case is scheduled for trial in April. (Associated Press)

Vulture talked to Jason Bateman at the Toronto Film Festival and found out that Mitch Hurwitz was not happy that Bateman inadvertently leaked, via a Twitter photo, about “The Workaholics” participation in the new episodes of “Arrested Development.” Also, Vulture reporter Jada Yuan says something about how his “Facts of Life” co-star, Lisa Whelchel , is going to be on “Survivor,” but Bateman was never on “The Facts of Life.” (She must have been thinking of “Silver Spoons,” a somewhat understandable mistake.) Anyway, he gamely plays along and it leads to a nice “Battle of the Network Stars” reference. So it all worked out. (Vulture)
