...Calum Best was copping an attitude whenever the subject of Lindsay Lohan came up! Geez, Calum, it's not like the details of you and Lindsay's relationship was top-secret material back when you two were "on" - why play coy now?

Speaking of playing coy, we also caught Avril Lavigne at Koi (well, sorta)! We also spotted Ian Ziering at Hyde, the Gastineau girls out and about, and Wilmer Valderrama and David Weintraub completing the bad-boy trifecta at Joseph's. But the weirdest collection of stars we saw last night had to be the triple threat of Mike Tyson, Barry Manilow, and Inside The Actor's Studio host James Lipton at Mr. Chow's! Wonder if they shared a table?
