Nikki Sixx of Mötley Crüe fame will be walking down the aisle for the third time. The 53 year old tattooed rocker slapped a 6 carat engagement ring on his 27 year old girlfriend Courtney Bingham. Nikki was previously married to Playboy playmate Brandi Brandt and has 3 children with her. He then married Bay Watch beauty Donna D’Errico which he has a daughter with. We wish Nikki and his new fiancée all the best. They say the 3rd time’s a charm.
