Machine Gun Kelly is finding the road to marriage harder than expected! The 31-year-old "Bloody Valentine" singer popped the question to his now-fiancée, actress Megan Fox, in January, and admitted on Thursday's "The Late Late Show with James Corden" that he's already run into an early wedding challenge. "When they can build me, like, a red river with gothic..." MGK said, before cutting off. "The location is hard, trying to find a spot that's matching my artistic [vision]," he added.
