Cityfile: New York's Most Notable and Influential

• Mischa Barton went to see "Tosca" at the Metropolitan Opera the other night. Naturally, when she showed up and saw a red carpet, she started walking it... until she realized it was for the screening of Michael Moore's new documentary at Alice Tully Hall. It was then that the light bulb went on and she ran across the street. Pull it together, woman! [P6]
• Jessica Simpson can't catch a break. Tony Romo ditched her; her dog got snatched by a coyote; her friends keep dishing to the media; and now her ex, Nick Lachey, appears to be reuniting with his ex, Vanessa Minnillo. Poor Jess. [E!]
• Tyra Banks appeared on Larry King Live last night and talked about how she dealt with packing on some lbs (again), her real hair (again), and how she loves being naked (unless the lighting in the dressing room sucks). [CNN, ET]More

• George Clooney's ex-girlfriend Sarah Larson may have cheated on the actor when she had a "weekend fling" with a "media mogul," although it appears she's paying for her crime since her new boyfriend is a lowly nightlife promoter named Joey Vanas. [P6]
• Lindsay Lohan says her dad is an "embarrassment and a bully" who won't stop talking about her to the press because he's addicted to fame. Sounds about right. [The Sun]
• Naomi Campbell's Russian billionaire boyfriend Vladmir Doronin picked her up a $18.5 million penthouse apartment in Sao Paolo as a gift. [P6] 
• The next socialite guest star on Gossip Girl? That would be Cristina Greeven Cuomo. [P6]
