Four months after giving birth, Tiffani Thiessen hit the Las Vegas strip -- where she had some PDA with her husband and showed off her post-baby bod!
Thiessen, who gave birth to baby Harper in July, was looking slim in a short black dress when cameras snapped her at the launch of kid's furniture line PetitNest at The Palazzo's VIP pool, AZURE last night.
Sources tell TooFab that the "Saved by the Bell" star was affectionate with husband Brady all night, and the two were even photographed sharing a smooch by the pool.
Tiffani arrived to the event after getting Harper to bed and, of motherhood, she says "Just remember to BREATHE! And laugh!"
