Lily Allen and David Harbour! The couple got married in in an extremely cute Las Vegas ceremony, they revealed on Instagram Wednesday, and I'm into every single aspect of it.Allen and Harbour made it official at Vegas' famous Graceland Chapel—and, naturally, an Elvis Presley impersonator officiated the ceremony. As British Vogue reports, Allen wore a gorgeous off-the-shoulder vintage Dior dress (very '60s!), complete with black buttons and a slim belt around the waist.
