Mischa Barton is rumored to have dumped Whitestar rocker Cisco Adler for rugby star Mark Robinson, after she was spotted in lip lock with him at a London hotspot recently. The 20-year-old O.C. actress had been dating the rock star, but reportedly hooked up with Robinson at a swanky party in Windsor, England.
"Mark couldn't believe his luck. One minute they were standing there talking and the next they were all over each other in the corner of the tent," Contactmusic quoted an onlooker at the bash, as telling British newspaper the News Of The World.
"They were snogging and running their hands over each other's bodies. They didn't seem to care who saw," the onlooker added.
But that's over now. Mischa's off to Australia to promote fashions of down under designers she can't remember the name of - hell, she couldn't even remember Robinson's name when she was asked about him: "I don't even know who Mark Robinson is," she told a reporter.
