Wearing a gown by Sarah Seven and Valentino heels, Mercedes, currently the on-air style expert on MTV's Girl, Get Your Mind Right! and a fashion blogger at Style Me Grasie, looked absolutely gorgeous alongside her new husband, who's the on-air host for Hulu's The Morning After and a DJ for LA's 104.3 MYFM.
Officiated by Dave Holmes, another former MTV VJ, the newlyweds celebrated with guests including Johnny Knoxville, Breaking Bad's Matt Jones, and Bridesmaids' Kali Hawk.
The couple, who met 10 years ago at MTV, actually can thank MySpace for eventually getting them together.
"Just before I moved to LA to act and host, I was a producer at MTV, while he was a VJ," Mercedes tells Us. "I thought he was cute then, but it wasn't until five years later when he contacted me on MySpace, that we start dating!"
Fahey, 33, is just excited to see what marriage life has in store for him. "Grasie and I are now part of the long list of couples that married after meeting at MTV years ago," he reveals. "We're excited to begin spending our lives together in silence while constantly staring at our iPhones."
Fahey served as the host of TRL from 2002 to 2008, when he took over for Carson Daly who went on to late-night TV.
