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!

And to add more strangeness, Jennie Garth’s character’s name on “What I Like About You” is Valerie. It’s like Tiffani and Jennie just switched names. š
Woah! I totally forgot about that! Thanks, Alyssa!
i got one more
jennie originally tried out for kelly on SBTB
then tiffany got it
Jeenie became kelly on 90210
the tiffany became valerie on 90210
the jennie became val on WILAY
and they were best friends
Hmm, don’t think I’ve ever seen anything about Jennie trying out for SBTB except in her IMDB bio. Guess it’s true then? Interesting!
I think I watched a SBTB E true hollywood story or something similar and it did say that Jennie auditioned for Kelly… how strange…
