Poison singer Bret Michaels has called off his engagement to longtime girlfriend Kristi Gibson, who is also the mother of his two daughters.

According to Life & Style Magazine the couple have parted ways after 16 years together.

"Bret and Kristi have called off their engagement at this time," Bret's rep tells the magazine. "Although the couple have separated, they remain great friends and are committed to jointly raising their two daughters, Raine and Jorja."

Michaels proposed to Gibson in December 2010 during the finale of his VH1 reality show, Bret Michaels: Life As I Know It.
