Former "90210" costars Tiffani Thiessen and Jason Priestley had a mini-reunion on Thursday, as they both brought their kids to Disney on Ice's "Let's Celebrate!" event in Los Angeles.
The two posed for a couple cute photos together -- and, while we love seeing the duo reunite, Priestley's precocious daughter Ava totally stole the show. Look at that expression ... just priceless!
Fellow "Beverly Hills" alums Tori Spelling and Lindsay Price also attended the event with their family, though didn't take any photos with their former costars. Same goes for Tiffani's former "Saved by the Bell" costar Mark-Paul Gosselaar, who was there with his wife Catriona McGinn.
McGinn was rocking (and cradling) a noticeable bump at the event. This will be their second kid together and Gosselaar's fourth.
Check out the gallery below to see all the cute, family photos from the event -- including shots of Malin Akerman, Brandon Routh, Alison Sweeney and more!
