Beep-ba-beep-ba-ba-ba-beep! Go baby! Tiffani Thiessen has welcomed her second child.
The "Saved By the Bell" alum, who now hosts the Cooking Channel series "Dinner at Tiffani's," announced the arrival of her son, Holt Fisher Smith, on Instagram on Thursday.
"Yesterday Harper got a little brother! We are so excited to introduce Holt Fisher Smith. Our perfect sweet little man. #weareblessed #familyoffour," the actress wrote, captioning a photo of her 4-year-old daughter, Harper, cradling the little guy.
The 41-year-old "Beverly Hills, 90210" actress announced back in January that she and her husband, actor Brady Smith, were expecting their second. The couple wed in July 2005 and had Harper in June 2010.
Thiessen's pregnancy was written into Jimmy Fallon's highly touted "Saved By the Bell" reunion in February. The "White Collar" actress donned her character Kelly Kapowski's old Bayside High cheerleading uniform and revealed her baby bump hiding behind those white pom-poms. The love child in that scenario belonged to her onscreen high school sweetheart, Zack Morris (Mark-Paul Gosselaar). Uh, doy!
