Sweeney has announced that she's pregnant with her second child, People reported Tuesday.

The 31-year-old Days of Our Lives star revealed the news while filming a segment for The Biggest Loser: Families, the sixth-season The Biggest Loser edition that NBC will air this fall.

"She told [The Biggest Loser: Families' cast] that, in a season all about family, hers is about to get bigger," Sweeney representative Carrie Simons told People.

Similar to last spring's The Biggest Loser: Couples, The Biggest Loser: Families will feature teams comprised of two adult family members, with Jillian Michaels and Bob Harper serving as the edition's trainers.

Sweeney and husband Dave Sanov already have a 3-year-old son named Benjamin.  The couple married in 2000.
