New Couple Alert! Carey Mulligan and Mumford & Sons Lead Singer Makin' Sweet Music Together

Actress finds new love with singer Marcus Mumford, the duo hooked up after a private concert

Carey Mullian is singing a new tune after moving out on Shia LaBeouf.

The Kewpie doll-like actress has found love again with Marcus Mumford, the lead singer of folk-rock band Mumford & Sons.

And it's gotten so serious so fast, the British actress has flown home from her base in New York City to live in the U.K. to be with her new honey.

So how'd these two hook up?

The 25-year-old An Education star, who split from LaBeouf in October after getting together in the summer of 2009 on the set of Wall Street 2: Money Never Sleeps, is currently with Mumford, 24, in Buckinghamshire. She also reportedly took a romantic trip last week with the "Little Lion Man" singer to the Orkney Islands in northern Scotland, according the U.K.'s Daily Mail. 

Mulligan, who was linked to Robert Pattinson's best bud Tom Sturridge after the LaBeouf split, has also been spotted lately hanging out at Mumford's home in Shepherd's Bush, London.

But their affair was reportedly sparked in Nashville, Tennessee last month after Mumford invited Mulligan to watch him play a private show in the basement of a pal's house in the music city. After a late night dinner together at the City House restaurant, where they carried on like a couple, it seems it was full blown love.

Mumford will be back in the U.S. next month to tour with his two-time Grammy nominated band. They will travel on a vintage train rather than a bus and Mulligan is rumored to be joining them for part of the tour. We think the actress, no stranger to roughing it, will have a blast.
