When viewers turn in to Dancing with the Stars tomorrow night, one star will be missing: co-host Samantha Harris.

How come? Because the lovely celebrity just gave birth to a girl!

According to People magazine, Harris and husband Michael Hess welcomed daughter Josselyn Sydney Hess Sunday morning at 1:49 a.m. in Los Angeles. She's the couple's first child.

"Michael and I are ecstatic to have a little girl to welcome into our lives," Harris told E! Online. "We can't wait to introduce her to our family and friends in the morning!"

ABC said it's not gonna to announce Harris's replacement; viewers will have to tune in to Monday night's Dancing with the Stars premiere to find out.
