Bret Michaels and Kristi Gibson have called off their engagement.
The on-again-off-again couple has separated, a spokesperson for Michaels confirmed to The Associated Press on Monday, July 30.
Michaels, 49, and Gibson, 41, have dated on and off for 18 years. They have two daughters together, 12-year-old Raine Elizabeth and 7-year-old Jorja Bleu. A statement from Michaels to the wire service says the two will "remain great friends and are committed to jointly raising" their daughters.
The couple initially got engaged in 2010 and the proposal aired on the finale of Michaels' reality show "Bret Michaels: Life As I Know It."
Michaels, the lead singer of the rock band Poison, became known for his dating exploits on the reality series "Rock of Love" which aired for three seasons between 2007 and 2009.
The rock star has suffered a few health problems over the past few years including a brain hemorrhage and a stroke. He also had heart surgery in January 2011.
In May, Michaels settled a lawsuit he filed over injuries he sustained while performing at the 2009 Tony Awards - an accident he said may have helped spur a near-fatal brain hemorrhage.
Poison was most popular in the 1980s with hits such as "Nothing But a Good Time" and "Every Rose Has Its Thorn." Michaels also won Donald Trump's "Celebrity Apprentice" in 2010.
