How does Mischa Barton know when she's found a classy guy? It's pretty simple, actually.
"When he pays for s--t," she told me last night at the party for Derek Blasberg's book Classy: Exceptional Advice For The Extremely Modern Lady.
Mischa was just one of the celebs out to toast the new tome. Kate Bosworth and Nicole Richie cohosted the party, which took place at the Missoni store in Beverly Hills, where Shenae Grimes, Malin Akerman and Balthazar Getty were on hand to celebrate.
And while Kate Bosworth's boyfriend, Alexander Skarsgård, wasn't there, we think he was probably the recipient of this flattering shout-out...
"I think it's pretty obvious, isn't it?" she replied when I asked her how she can spot a classy dude. "It shouldn't really be a thoughtful thing. You just know!"
As for the classiest person Kate knows, she chose someone else near and dear to her.
"Hands down, my mother," she said. "I'm sure that's what many, many women say, but in my case, it's nothing but the truth." Well said!
