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.

Barton, 22, is known for her role as Marissa Cooper on the TV series 'The O.C' and previously dated rocker Cisco Adler, front man for the band Whitestarr.

The rumors come right on the tail of the report that Barton was dating Brett Simon. Simon is the director of her latest film, "The Assassination of a High School President" which co-stars Bruce Willis and Rumor Willis.

Barton's representatives have not commented on either of the romance rumors.
