J.R. Martinez is newly single. The 30-year-old actor has split from his longtime girlfriend Diana Gonzalez-Jones, Us Weekly can confirm. The two recently welcomed their daughter, Lauryn Anabelle, just 18 months ago.

"Diana Gonzalez-Jones and I have ended our relationship," Martinez tells Us in a statement. "However, we are committed to working together to raise our daughter in a healthy and happy environment."

Just one day earlier, the Iraq war veteran wrote a telling message on his official Facebook page. "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…" he wrote on Jan. 8.

The Season 13 Dancing with the Stars champ and Gonzalez-Jones first met on the set of All My Children in 2008. In November 2011, the pair announced they were expecting their first child together.

"I was so focused mentally, emotionally, on Dancing with the Stars and then I was also processing, 'Whoa, I'm going to be a dad!'" Martinez told Us of the baby news that December. "That's a lot of information to process at one time! When she initially told me, I was so excited."
