Peter Facinelli - Lily Anne Harrison Welcome their First Baby's Birth

The birth of Peter Facinelli and Lily Anne Harrison's first child has been revealed.

The newborn was greeted on Monday by actors Facinelli, 48—best known for his role in the Twilight movie series—and Harrison, 33—most recently seen in The Vanished.

Facinelli announced the baby's arrival on Instagram. Their child's gender has not yet been made public.

Facinelli tweeted "Happy 'Labor' Day' @lilyanneharrison" with a photo of himself holding his newborn child. "Sept. 5, 2022."

The couple's first kid together is this one. Luca, 25, Lola, 19, and Fiona, 15, are the three former children Facinelli had with his ex-wife Jennie Garth.

Harrison initially made her pregnancy known in a June Instagram post.

The caption on Harrison's photo said, "Not a burrito tummy," and it showed Harrison with the beginnings of a baby bulge.

Over the next months, Harrison would post more behind-the-scenes images of her pregnant experience.

She recently spoke to News about her pregnancy and said, "It's been extremely smooth and uncomplicated."
