J.R. Martinez and his longtime girlfriend Diana Gonzalez-Jones are calling it quits on their relationship although they're new parents to a baby girl.

"Diana Gonzalez-Jones and I have ended our relationship," Martinez, the thirteenth-season Dancing with the Stars champion, told Us Weekly in a statement.

"However, we are committed to working together to raise our daughter in a healthy and happy environment."

The Iraqi war veteran and former All My Children soap star suggested Gonzalez-Jones became a different person over time.

"People change its a part of life, but sometimes its easier to hold on to the memories of who they were rather then to realize who they have become," Martinez wrote on his Facebook Fan Page January 8.

Martinez and Gonzalez-Jones welcomed a daughter, Lauryn Anabelle Martinez, in May 2012. The couple announced they were expecting their first child together in December 2011, only one month after Martinez had been crowned Dancing with the Stars' winner with professional partner Karina Smirnoff

Martinez and Gonzalez-Jones, who started off their relationship as friends, initially met at work in 2008 on the set of All My Children. While Martinez was acting in the show, Gonzalez-Jones was serving as the executive producer's assistant.
