Remember this for a future trivia question:
Tiffani Amber Thiessen (Valerie, Beverly Hills 90210) is best-known for playing Kelly on Saved by the Bell.
But in the world of 90210, Thiessen’s character is best-known for feuding with a Kelly–this one played by Jennie Garth.
In real life during the 90210 years, Thiessen and Garth were actually best friends.
And, to go in a different direction: Valerie’s frenemy is Tori Spelling’s Donna.
Spelling appeared alongside Thiessen on Saved by the Bell, as the nerdy outsider Victoria Bickerstaff.
Oh, what a tangled web they weave!
