Mandy Moore, Ryan Adams

Having dated on and off since March 2008, Mandy Moore and musician Ryan Adams couldn’t wait to take the plunge after they got engaged in February 2009. Just one month later, the couple decided to get hitched in an extremely low-key, last-minute ceremony officiated by Pastor Steve Schulte, who revealed to People that one of their reps had arranged for him to marry the couple at the Whitefield Chapel at Bethesda Home for Boys near Savannah, Georgia, only the day before. Aside from Mandy and Ryan, only the pastor was in attendance, making it a very causal-yet-romantic wedding indeed. Three years later, it sounds like their marriage is as relaxed as their nuptials were. "We're big homebodies. We never want to leave [the house],” the actress-singer told People. "I feel very supported and loved and at peace. My life has reached this really beautiful point where I can sort of look around and go, 'Wow. I'm so lucky.' I got my own little happy ending."
