Jana Kramer and Mike Caussin
Shortly after the former NFL star checked himself into rehab for unknown reasons, news broke that the duo had separated in August. While Jana and Mike have yet to comment on the news, a source close to the pair told ET that the singer has been "trying to put on a brave face and do what's best for her daughter. She's been devastated by this." The couple first began dating in 2014, and earlier this year, they welcomed their first child, a baby girl named Jolie Rae.
