has a new boyfriend.
The former 'O.C.' actress is dating
British DJ Ali Love and the couple went public with their romance at London festival Lovebox over the weekend, where onlookers say they couldn't keep tier hands off each other.
A source told the Daily Mirror newspaper: "Mischa was looking pretty merry in a bedraggled short flowery dress and white bow. She and Ali were all over each other backstage, and kept popping off to the toilets - presumably for a cheeky kiss.
"They just returned from a break in the South of France and things are obviously going really well."
Mischa - who has been linked with a string of famous men, including singers Luke Pritchard and Johnny Borrell - recently said she was looking for a new man.
She said: "I'm not even dating. I'm just on the prowl I suppose."
She also revealed how she has never been dumped and said the closest she had came to getting her heart broken was when a relationship ended mutually and she just got angry with the boyfriend for not letting her end the romance alone.
She said: "I've never been dumped. One tried to make it quite mutual though so that felt as close to dumping as I've got. I kind of lost it and was like, 'You are not turning this on me. I dumped you first.'
"I felt like my heart was broken at the end of a couple of relationships
but it wasn't really."
