The couple, who met on season 9 of the hit NBC series, are expecting their first child in July
Nobody is winning in this situation.
“It is with great sadness that my marriage to Sam Poueu is ending,” Anderson tells PEOPLE in an exclusive statement. “Thank you in advance for respecting our privacy during this difficult time.”
The two, who met on the hit NBC show’s season 9 and wed in April 2012, are in the process of divorcing – but no papers have been filed yet.
Poueu, 28, proposed to Anderson, 33, during a special episode of the Biggest Loser in 2010.
Before their wedding, he suffered serious injuries after a fall from the roof of a four story building in 2011 and spent nine months in recovery. Shortly after, he admitted to Anderson that “he wanted to have children and grow old with me,” she said at the time.
The couple announced in January that they were expecting; they’ll welcome a baby boy in July.
