Tiffani Thiessen Welcomes a Baby Boy

Tiffani Thiessen welcomed her second child, a baby boy, on Wednesday. She announced the exciting news via Instagram, sharing a sweet photo of her 5-year-old daughter, Harper, holding her new baby brother, writing, '"Yesterday Harper got a little brother! We are so excited to introduce Holt Fisher Smith. Our perfect sweet little man."

The former Saved by the Bell star and her husband, Brady Smith, revealed that they were expecting back in January; Tiffani later brought her baby bump to The Tonight Show for a hilarious Saved by the Bell reunion, wearing a maternity version of her Bayside Tigers cheerleading uniform.

Tiffani joins a group of former '90s stars who have welcomed their second children recently; Rachael Leigh Cook and Jennifer Love Hewitt also gave birth to baby boys, while Tamera Mowry brought home a little girl this week. Keep reading to see Tiffani's sweet snap.
