You may remember her as Kelly Kapaowski from hit teen series Saved By The Bell, but these days she’s spending less time hanging out at The Max and more time changing nappies.

The 41-year-old and husband Brady Smith have welcomed a new addition to their family; a beautiful baby boy.

Tiffani shared a snap on her Instagram account of their pride and joy with their 5-year-old daughter Harper to mark the occasion.

She wrote: "Harper got a little brother! We are so excited to introduce Holt Fisher Smith.

"Our perfect sweet little man. #weareblessed #familyoffour (sic)"

The 90s pin-up revealed that Harper was very eager to meet her new sibling.

Tiffani said in an interview before the birth: "With Harper, it happened right away so I'm hoping it'll be easy this time around. Every day she begs me to have a baby.

"Every morning she wakes up and days, '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!'"

Following her time on Saved By The Bell, Tiffani launched her own production company.

She then went on to star in popular crime series White Collar alongside Magic Mike star Matt Bomer.
