Time out! How cute are these two!? Tiffani Thiessen and her actor husband, Brady Smith, welcomed their second child on Wednesday, July 1. The Saved by the Bell alum announced the news by posting an Instagram snapshot of big sister Harper holding the newborn on Thursday.

"Yesterday Harper got a little brother!" Thiessen, 41, captioned the adorable photo. "We are so excited to introduce Holt Fisher Smith. Our perfect sweet little man. #weareblessed #familyoffour."

Thiessen and Smith, 43, married in 2005 and welcomed daughter Harper in June 2010. Back in January, the couple revealed they were adding to their family.

In 2013, Thiessen explained why she didn't feel the need to have a nanny shortly after Harper's arrival. "It's definitely a challenge," she said during HuffPost Live that February. "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."

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