Carey Mulligan and Marcus Mumford touched down at LAX together yesterday. The married duo stayed side by side as they exited the terminal and waited for their ride to arrive. Marcus and his band, Mumford and Sons, have had a busy Summer touring, and Carey's been able to accompany him to many of their gigs. She's also got her own big-screen career to focus on, though the opening of her next release, The Great Gatsby, was delayed until January 2013. Carey will star in Nancy and Danny, a black comedy, next. There are also rumors about another project — according to reports, Carey might be pregnant.
