Mötley Crüe bassist Nikki Sixx is engaged to his girlfriend of the past two years, model Courtney Bingham.

Nikki said: "We're beyond happy and in love."

You may remember Bingham celebrated her 27th birthday by performing a striptease to the Mötley Crüe song "Girls, Girls, Girls" during the band's concert this past September in Michigan.

Sixx and Bingham have been dating since 2010, just after Nikki broke up with tattoo artist Kat Von D.

53-year-old Nikki has been married twice--to Playboy Playmate Brandi Brandt and actress Donna D'Errico. He has five children.
