“>Saved By The Bell and husband Brady Smith have welcomed their second child, a boy, on Wednesday.

The 41-year-old actress shared the news via Instagram on Thursday with an adorable photo of 5-year-old daughter Harper Renn holding the newborn.

Tiffani Thiessen’s adorable post included the caption, “Yesterday Harper got a little brother!” Tiffani captioned the shot. “We are so excited to introduce Holt Fisher Smith. Our perfect sweet little man. #weareblessed #familyoffour.”

The couple kept their pregnancy news on the download until January, but Tiffani hinted that the family would soon add to their family when she told Access Hollywood Live a month before the big reveal that little Harper was already looking forward to being a big sister.
