It appears things will heat up between Shannen Doherty (Samantha Munro) and Jason Priestley (Max Lloyd-Jones) in Lifetime’s The Unauthorized Beverly Hills, 90210 Story.

In a clip from People, Shannen and Jason get pretty flirty while reading a scene in front of producers. The thing is they’re reading as fraternal twins Brenda and Brandon Walsh.

It gets to the point where the original show’s creator Darren Star (Adam Korson) has to interrupt them. “I just want to remind you again that you’re siblings,” he says, but the flirtation continues anyway.

Check out the clip below, and head to People for more.

The Unauthorized Beverly Hills, 90210 Story will show the on- and off-set drama amongst cast members and producers during the original show’s first four seasons. It premieres on Saturday, October 3 at 8 p.m. ET on Lifetime.
