Who's Kirsten's new guy?

A few pictures were shot this weekend of Kirsten Dunst getting cozy Razorlight singer Johnny Borrell at the SXSW festival in Austin, sparking curiosity about the Marie Antoinette star's love life. After a brief reported hookup with Drew Barrymore's ex and Strokes drummer Fabrizio Moretti, Dunst met Borrell at his band's LA show on March 9, where the British rocker is said to have invited his new actress friend to Austin. The new couple were spotted all kissing and dirty-dancing all over town. "They are definitely together," said an onlooker. "They were all over each other." Dunst showed her support for new beau by showing up at his band's gig on Friday night. "Kirsten was there rocking out and just got really into him," said a source. "She and her friend went right to the side of the stage and danced like crazy to every song. She was in a great mood, knew every word and was mesmerized by Johnny. She kept calling things out to him and giggling." The lovebirds met backstage after the show for a liplock, says the source.
