The actress, 24, who split from Shia LaBeouf in late October, has reportedly moved on to fellow Brit, Marcus Mumford, lead singer for Grammy-nominated folk band Mumford & Sons.
The couple have recently been spending time together at Mumford's London home and in Buckinghamshire, England, according to the Daily Mail. The pair also spent last week in the Orkney Islands.
Last month, Mulligan was spotted looking cozy with Mumford, 25, during his band's gig at St. Magnus Cathedral in the U.K.
"They were kissing and cuddling in public," an onlooker from the night tells PEOPLE. "They were clearly very fond of each other. They were very, very affectionate to one another."
Mulligan, who otherwise kept a low profile at the show, "was very quiet and just kind of sat behind the scenes," says the onlooker.
Mulligan's rep had no comment.
