Carey Mulligan, Marcus Mumford Engaged

Mumford & Sons frontman and 'An Education' actress have been dating for five months.

Carey Mulligan is about to get “an education” in marriage.

According to Us, Mulligan is engaged (for real this time) to boyfriend Marcus Mumford. The Mumford & Sons frontman, 24, reportedly popped the question to Mulligan, 26. The pair first got together five months ago, when the “Drive” actress went to a secret Mumford & Sons show with her buddy Jake Gyllenhaal. (Mumford and Mulligan are also said to have been childhood pen pals through their church in London.)

Their supposed engagement was first reported on July 26, but Us claimed on Wednesday (August 3) that they got the latest scoop from an insider close to the couple. “They’re a great couple,” the source told the magazine, “very sweet.”

Both stars had recently split with their significant others when they reconnected in February. Mulligan split with her longtime boyfriend and “Wall Street: Money Never Sleeps” costar Shia LaBeouf in October, while Mumford broke up with singer Laura Marling around the same time.

When MTV News caught up with the Oscar-nominated Brit at San Diego Comic-Con, she was keen to talk about the other love story in her life: Baz Luhrmann’s adaptation of “The Great Gatsby.” It turns out, despite her fiancé’s musical chops, she’s not too keen on joining the ranks of actresses who sing and dance in Luhrmann’s films.

“No singing,” Mulligan said emphatically. “As I say, it’s been eight months since I got the job, so I’ve had a lot of time to think about it.”
