Carey Mulligan and her husband Marcus Mumford stepped out for a sweet stroll in NYC today. The couple has been splitting time between the Big Apple and their home in London since Marcus wrapped up the first leg of an overseas tour with his band, Mumford & Sons, earlier this month. While in Manhattan last week, Carey hit the red carpet in a Victoria Beckham suit for the Tiffany & Co. Blue Book Ball, where she partied with Gwyneth Paltrow, Kate Hudson, and Michelle Williams. She also graces the cover of Vogue's May issue while channeling her Great Gatsby character, Daisy Buchanan. The next few weeks will likely be a busy time for the couple. Mumford & Sons sets off for the remainder of their world tour in Canada, and are nominated at next month's Billboard Music Awards, while Carey will begin making the press rounds for Great Gatsby ahead of its May 10 release.
