"It is with great sadness that my marriage to Sam Poueu is ending," Stephanie says. "Thank you in advance for respecting our privacy during this difficult time."
The couple were married in April 2012 and recently celebrated their first anniversary. Stephanie is currently seven months pregnant with their child.
Stephanie and Sam met during Season 3 of The Biggest Loser, which aired back in 2010. He proposed on the show's ranch in October 2010.
The couple have been faced with (literal) ups and downs since then, as 27-year-old Sam was badly hurt after falling 54 feet from a roof deck in September 2011. Stephanie was at his side during the difficult three-month recovery.
The couple seemed to be in a good place when announcing their pregnancy in January of this year.
"Sam has been wonderful," Stephanie said at the time.
And Sam returned the praise, saying in January: "Just from the experience of her being my caretaker post-accident, it was a dead giveaway that she'd be a fantastic mother." Tears!
We're wishing the best for their soon-to-arrive bundle of joy.
