Jennie Garth & Tori Spelling Address '90210' Shannen Doherty Drama

"Beverly Hills, 90210" stars Jennie Garth and Tori Spelling seem to be airing out all the drama that's happening on their reboot set, taking to social media to share a back and forth convo that has fans wondering if they're talking about Shannen Doherty.

Spelling turned 46-years-old on Thursday and celebrated the way any working actress does -- onset filming. Sharing a photo holding cupcakes and posing alongside Garth and Jason Priestley, the star wrote, "Even though we were working all day and doing wardrobe on my bday I was happy to share my bday cupcakes with my friends @jenniegarth and @jason_priestley."

Seems innocent, right?

It's Garth's birthday tribute to her '90210' best friend that has fans raising their brows, because it seems the two are subtly confirming the rumors that there's drama onset ... all reportedly started by Doherty.

"Happy birthday to my partner and best friend for life. Wow, we’ve been thru some s*#t! And today was no exception!" Garth wrote.

Spelling responded, confirming the day onset had been a rough one.

"Thru thick and thin... birthdays are just tests and I can pass any test with you by my side!" she posted.

On Friday, Doherty fired back at the claims she was responsible for staff quitting the show, saying, "Being a part of tv history is an honor but it also comes with some massive backlash." Adding that she has "a fear of doing what I love because of headlines like this."

"90210" is (hopefully) set to premiere on August 7.
