Snooki pregnant with her third child

Nov. 23 (UPI) -- Jersey Shore and Dancing with the Stars alum Nicole "Snooki" Polizzi announced on Instagram she is pregnant with her third child.

"What I'm thankful for this Thanksgiving #family," Polizzi captioned Thursday's photo of her son Lorenzo, 6, and daughter Giovanna, 4, holding a framed sonogram image of their younger sibling.

A second photo shows the children looking comically dismayed about the new addition to the family.

Polizzi did not say when she is due to give birth or what the child's sex is.

Polizzi was recently seen in Season 2 of Jersey Shore Family Vacation.
