What could be more appropriate than Biggest Loser host Alison Sweeney first announcing the expansion of her own family to the cast of Biggest Loser: Families? Nothing, apparently.

According to People, the Days of Our Lives star did just that Monday night, telling the gang that she and husband are expecting a second child. "She told them that, in a season all about family, hers is about to get bigger," said the star's rep.

Sweeney and husband Dave Sanov already have a 3-year-old son named Ben. - Adam Bryant
