Sad news, Dancing With the Stars fans: Season 13 champ J.R. Martinez has split from his girlfriend, Diana Gonzalez-Jones.

J.R. spoke to People about the split, saying simply, "Diana and I have ended our relationship. However, we are committed to working together to raise our daughter in a healthy and happy environment."

J.R. and Diana had been in a relationship for four years, and Diana gave birth to their baby girl,  Lauryn Anabelle Martinez, in May of 2012. J.R. did not go into detail about what caused the split, though a recent post on his Facebook page hints at what's happening in his private life.

"People change, it's part of life," J.R. wrote. "But sometimes it's easier to hold on to the memories of who they were rather then to realize who they have become..."

This news will certainly come as a disappointment to J.R.'s many fans. The Iraqi War vet turned soap star won America's heart completely on Dancing With the Stars Season 13. He easily waltzed his way to the top with partner Karina Smirnoff, thanks to his combination of graceful movement, entertainment value, and kind spirit.

We're sad to hear about this development, and we wish J.R. and Diana the best of luck in what must be a difficult period.
