MÖTLEY CRÜE bassist Nikki Sixx has proposed to his girlfriend of the past two years, model Courtney Bingham. Nikki states, "When Courtney and I were in St. Barts, I popped the question and she said yes.. We would like to thank everybody who has been tweeting and posting us online congratulations. Both of us and our families are beyond happy."

Bingham celebrated her 27th birthday by performing a striptease to the MÖTLEY CRÜE song "Girls, Girls, Girls" during the band's September 6 concert at DTE Energy Music Theater in Clarkson, Michigan.

After the show, Sixx said in an online posting, "It was a blast for me watching Courtney get all excited to dance on stage with our background dancers for her birthday. She really kicked ass, too."

Sixx and Bingham have been dating since 2010, shortly after the breakup of his relationship with tattoo artist Kat Von D.

In his autobiography, "Tattoos & Tequila: To Hell and Back with One of Rock's Most Notorious Frontmen", MÖTLEY CRÜE singer Vince Neil took aim at Sixx for his dating habits, writing, "Just like Tommy [Lee, MÖTLEY CRÜE drummer], [Nikki's] another one of those guys who just love the whole fame thing. He wouldn't have been with the tattoo artist Kat Von D if she wasn't famous. And [former 'Baywatch' actress] Donna D'Errico before her; she was a huge star at the time he married her. He just really likes to see his face in the paper. He likes the press buzz. He likes being that guy from the band with famous girlfriends."

Sixx, 53, has been married twice, to Playboy Playmate Brandi Brandt and actress Donna D'Errico, and has five children.
