Tiffani Theissen and her husband Brady Smith have welcomed a new baby boy on July 1, and the Saved By the Bell alum shared the news by posting the cutest picture on Instagram.

Posted on Thursday (July 2), the photo shows her 5-year-old daughter, Harper, holding her baby brother. "Yesterday Harper got a little brother!" the 41-year-old actress and TV cook wrote in the caption, which you can see below. "We are so excited to introduce Holt Fisher Smith. Our perfect sweet little man. #weareblessed #familyoffour."

Tiffani and Brady had been married since 2005 and had their first child in June 2010. They announced that they were expecting in January.

Despite being busy with her various appearances and hosting Dinner at Tiffani's on the Cooking Channel (YES! Kelly can cook!), Tiffani told HuffPost Live that she didn't want to have a nanny watch her kids -- at least, for now.

"It's definitely a challenge," she said in 2013. "My mother is a very, very big part of our lives and helps us so much so it allows us not to have a full-time nanny. It may not always be that way, but luckily we are able to do that."

She also added, "I love that I have the kind of job that I don't have to work every day. Kid number two or three I'll probably need some more help!"

Congratulations to Tiffani, Brady and big sis Harper!
