The Penguin Returns to Gotham City

7/15/2008 6:36 PM PDT
The Penguin flew solo to a "Dark Knight" after-party in NYC -- where the cast of the flick was absolutely swarmed by autographazzi and pappers staked outside.

Also in NY: Heath Ledger's ex-gf Naomi Watts showed up to the party for support too, Billy Crystal said Madge was a hottie, Ethan Hawke dodged Uma wedding rumors and Gabrielle Union put the A-Rod/Madonna gossip on blast.

In L.A.: Sports stars flooded LAX, the luckiest guy alive escorted Adriana Lima through the airport, Lindsay Lohan was in a foul mood and Robert Kardashian Jr. was clueless about his sis' upcoming jail stint.
