She may have popped over to see "some friends" in London, but Mischa Barton
couldn't help gushing Wednesday night about her other life
across the Channel, in Paris.
"I love the art and the museums. So far I have been hanging out, really – going to art exhibitions, lots of museums. I'll have my place there for about a year," the leggy, former O.C.
star, 22, told PEOPLE at Pharrell Williams's launch of his clothing brands Billionaire Boys Club and Ice Cream footwear at Harvey Nichols – which was the favorite department store of Absolutely Fabulous
's Patsy and Edina.
Barton liked what she saw there, too: Williams and his band N.E.R.D. "I am a fan," she said. "I like to have a feel of different performers, so I am curious to see."
Williams didn't disappoint – performing four songs (among them, the hit "She Wants To Move"), showing off his abs to the cheering crowd and even delivering a peck or two to a couple of lucky female fans.
