Tiffani Thiessen admits to drinking wine at 16 with 'Saved By the Bell' co-star Mark-Paul Gosselaar

Tiffany Thiessen is serving up a serious side of '90s nostalgia on her upcoming Cooking Channel special, "Christmas at Tiffani's," where she gathers around the dinner table with her husband, Brady Smith, and three of her former on-screen loves.

Thiessen's "Saved by the Bell" co-star Mark-Paul Gosselaar, her "Beverly Hills, 90210" flame Jason Priestley and her "White Collar" love interest Tim DeKay made themselves helpful in the Thiessen kitchen along with their respective wives, Catriona, Naomi and Elisa.

Naturally, discussion eventually turned to their past work together. Thiessen and Gosselaar reminisced about their time on "Saved by the Bell."

"My love of food kind of started a little bit with you, traveling through Europe like we did when we were teenagers," Thiessen told Gosselaar.

"It was a paid trip to Paris, and we'd just go to the finest restaurants," Gosselaar recalled.

"Do you remember when we went to Bordeaux?" Thiessen chimed back in. "We had that amazing meal with like seven glasses with different types of wine."

The table burst into laughter when Thiessen revealed that they were just 16 at the time.

"We did a lot of things back then," Thiessen admitted.

"No social media," Gosselaar explained. "It was awesome!"
