Baby No. 2! Tiffani Thiessen is pregnant and expecting her second child with husband Brady Smith, Us Weekly can confirm. The White Collar actress and her artist husband are already proud parents to 4-year-old daughter Harper.

"We are excited to announce the news that we are expecting," Thiessen shared on Instagram as well. "Harper could not be more thrilled to have a sibling and a playmate."

And the news couldn’t be more exciting for Thiessen, 40, who has been vocal about her entire family wanting to expand their brood.

“Every day, she begs me to have a baby,” Thiessen told Sweden With Love magazine of her daughter Harper. “She can’t wait to turn into a little mommy. She’s ready!”

The Saved by the Bell alum will surely have her hands full though, if her second child is anything like her first. 

“She was the kind of baby that would never fall asleep!” she told the mag. “I would be nursing her, and she’d be wide awake. All these other mothers would tell me their kids would fall asleep the minute they started nursing them, but that wasn’t my kid!”

Thiessen and Smith have been married since 2005.
