Everyone - from Justin Timberlake and Nick Lachey to Samantha Ronson and Rumer Willis - was out on the town last night! And speaking of Rumer, what is UP with that hair? Did she have a bottle of peroxide that was about to expire or something? Damn! Meanwhile, Lachey and Vanessa Minnillo were at Opera (as was deejay Sam and Timberlake) and Colin Farrell showed up at the Roosevelt. Other celebs spotted included Topher Grace, Eric Mabius, Joey Fatone - who does not want to see himself in a sex tape! - Ne-Yo, Danny DeVito and Tricky.

But seriously, back to Rumer: Hot or not?
