Tiffani Thiessen and her husband, Brady Smith, have welcomed their second child. Thiessen gave birth to a baby boy earlier this week.

The couple named their new bundle of joy Holt Fisher Smith, who joins older sister Harper, 5.

"Yesterday Harper got a little brother!” Thiessen wrote on Instagram. “We are so excited to introduce Holt Fisher Smith. Our perfect sweet little man. #weareblessed #familyoffour.”

The coupe announced back in January that they were expecting their second child. At the time she said in a statement “Harper could not be more thrilled to have a sibling and a playmate.”

She has previously talked about the “pressure” Harper put her under to give her a sibling, saying “Every day she begs me to have a baby. Every morning she wakes up and says, 'Is there a baby in your belly?' She thinks it grows overnight while we're sleeping. Then she looks at me and says, 'You're not growing a baby, Mommy!'"
