Poison frontman Bret Michaels and his girlfriend of 18 years, Kristi Gibson, have called off their engagement.

Michaels proposed to Gibson in 2010 on an episode of the reality television show ‘Bret Michaels: Life As I Know It.’

The former couple have two daughters Raine Elizabeth 12, and Jorja Bleu, 7. Michael’s rep told ‘People,’ "Although the couple have separated they remain great friends and are committed to jointly raising their two daughters."

Over the years the on-again, off-again relationship has survived a lot of hardships with Michaels' numerous health issues such as an emergency appendectomy, a stroke and a brain hemorrhage that practically ended his life.

Back in 2007-08, Michaels also had another reality show called ‘Rock of Love with Bret Michaels’ which lasted two seasons, where broads duked it out in order for his affection. Perhaps we will see another installment of this dating reality show, now that Michaels is back on the market?
