It has been reported that Carey Mulligan has been quietly dating Marcus Mumford, lead singer of the British folk band Mumford and Sons.

The Daily Mail reports that the actress is supposedly "besotted" with the singer, and the couple enjoyed a romantic weekend together in Buckinghamshire, England, after spending last week together in the Orkney Islands in Scotland.

An insider is reported saying, "They've also been spending time at Marcus' London home in Shepherd's Bush."

The pair first got together last month in Nashville, Tenn., where Mumford invited Mulligan to watch him play at a show in his friend's house.

An insider is quoted saying, "She sat in the front row, and while he was singing, Marcus looked down at Carey, and she blushed. It was clear they had chemistry."
