Welcome to the world, kiddo! Biggest Loser champ Olivia Ward welcomed her first child, a baby boy, with husband Ben Ward on Friday, Aug. 14, she announced via Instagram.

"It is with overwhelming joy @benwardmusic and I would like to introduce our son Harper Ellis Ward," the proud new mom captioned a photo of her newborn son. "Born 8-14-15 weighing 8 lbs., 6 oz. We couldn't be more grateful to God for this amazing gift!"

The reality star, 39 — who won Season 11 of NBC's hit weight-loss series — first revealed her pregnancy exclusively to Us Weekly back in February. "My husband Ben and I are so thrilled to be expecting," she gushed at the time.

The news was especially sweet given Ward's past struggles to conceive. As she shared in 2013, she had a difficult time getting pregnant because of polycystic ovarian syndrome, a hormonal condition that can also cause weight gain.

"To say I feel beyond blessed is an understatement," she told Us in February. "We have wanted children for a long time, which makes this gift so incredibly special."

Now a SoulCycle instructor in New York, the former opera singer endeared herself to fans during her 2011 stint on The Biggest Loser. She competed alongside her sister Hannah Curlee, dropping an incredible 129 pounds on the show.
