After five months of dating, Mumford popped the question last August. The couple has a long history, as Mulligan and Mumford were childhood pen pals. They reconnected in February 2011 at a Mumford & Sons concert and have been dating since.
Mulligan was previously attached to Shia LaBeouf, while Mumford split from folk singer Laura Marling in 2010.
