Mischa Barton is reportedly quitting Hollywood.

The former 'O.C.' actress is reportedly planning to move to London to settle down with her new boyfriend, DJ Ali Love, who she has been dating for just a month.

A source close to the star told heat magazine: "Mischa's found a great new guy. She can't wait to move to London to be with him. It's already in the works."

The 24-year-old star is also hoping to launch a stage career and has set her sights on landing a leading role in a production in the UK capital's West End theatre district.

The friend added: "Instead of Hollywood gigs, Mischa's focusing on a stage career in the West End. She wants to spend a year in London and see where things go with both the theatre and Ali. She's so happy to be starting afresh. She's so in love!"

Mischa has previously stated she "feels more comfortable in England", where she was born and lived until she was six years old.

The actress - who has been linked with a string of famous men, including singers Luke Pritchard and Johnny Borrell - went public with her romance with Ali at London's Lovebox festival last month.

A source said at the time: "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."
