Mischa Barton spent Monday evening with Josh Hartnett.

'The O.C.' actress - who recently split from her musician boyfriend Taylor Locke - met up with the '30 Days of Night' actor at exclusive London nightclub Bungalow 8 and after chatting together the pair reportedly left for his hotel at the end of the night.

Mischa Barton has dumped her boyfriend Taylor Locke. "The O.C." actress reportedly called time on her relationship with the Rooney guitarist shortly after they returned home from a three-week safari and charity trip to Africa.

A source said: "They fought almost every day on the trip. She broke up with him just a few days after they returned to Los Angeles."

Mischa Barton is proud of her curves. The actress - who was recently photographed in a bikini showing visible signs of cellulite - says as long as her rocker boyfriend Taylor Locke likes her body, she is happy.

She said: "I have a woman's body. I have hips and boobs so when I gain any weight it goes straight there, which I don't mind because it gives me curves. But it goes straight there."

It looks like there is a new couple in Hollywood for the paparazzi to stalk. Actress Mischa Barton is rumored to be dating the guitarist for the band Rooney, Taylor Locke.

Barton was spotted at the Roxy for a memorial concert for filmmaker Brandon Schantz, where Locke's bank performed. After the show, she was spotted backstage and was rumored to be seen holding him around the waist and kissing him on the lips. People Magazine also snapped a picture of the couple having lunch in West Hollywood.
