Marcus Mumford is set to marry actress Carey Mulligan in April.
The pair, who met around a year ago in Nashville, Tennessee, reportedly are set to tie the knot in the UL in April.
A source told The Sun: "Both Carey and Marcus have been so busy recently.
"She's been filming The Great Gatsby in Oz and he has locked himself away in the studio with the rest of Mumford & Sons to record their new album.
"They've finally got around to choosing a date and place for the wedding and sent out all of the 'save the date' cards to guests. They decided it makes sense to have the nuptials in Britain because it's where both of their families are from."
The Mumford & Sons frontman previously dated fellow folk singer Laura Marling.
The band are currently working on the follow-up to 2009's 'Sigh No More', which is said to be more 'mature' than their debut.
