BRET MICHAELS has called off his engagement to Kristi Gibson.

The 'Every Rose Has Its Thorn' hitmaker has ended his relationship with Kristi, his girlfriend for more than 16 years, but they hope to remain ''great friends'' and are ''committed'' to raising their two daughters, Raine Elizabeth, 12, and seven-year-old Jorja Bleu.

The 49-year-old singer's representatives said: ''Although the couple have separated they remain great friends and are committed to jointly raising their two daughters.''

Bret's proposal to Kristi was aired on his reality TV show, 'Bret Michaels: Life As I Know It', during the show's finale in December 2010, and the Poison frontman is now planning to create a biopic of his life.

He told the Columbus Dispatch: ''I want to tell the story. Mostly, when you see rock movies, it has to be this over-the-top thing. I want to give people a Bret Michaels movie where they see that my life is a comedy of Errors. I also want to show my fans how to get through the kind of troubles that would leave most people flat on the floor.''
