Alison Sweeney Leaves Biggest Loser After 13 Seasons Returns to 'Days of Our Lives'

We didn't see this one coming. While fans of NBC's The Biggest Loser have watched as contestants have lost massive amounts of weight over the last 16 seasons of the weight loss series, there is news today that the NBC reality competition is about to suffer one of the biggest losses yet. It was just revealed that after being with the show for 8 years, and 13 seasons, Alison Sweeney has decided to part ways with the show. That's right; the Days of Our Lives actress announced that she will be sitting season 17 out.

Access Hollywood is reporting that a statement was released from show's camp early this week, stating, "After and incredible run together, Alison Sweeney will not be returning as host of The Biggest Loser next season."

The star has been with the show since 2007 when she took over for host and Sabrina the Teenage Witch star, Caroline Rhea. Rhea was with the show for the first three years before being replaced by the soap opera actress.

She departed the show back in 2014, but fans best know her for her role as Sami Brady, in addition to her hosting duties on the NBC reality series.
