Tiffany and Deborah Gibson

No, it's not 1987, but Debbie Gibson and Tiffany are facing off again — this time on screen.

The former '80s pop stars will resume their "rivalry" in Syfy's new original movie, Mega Python vs. Gatoroid, the network announced Thursday.

Gibson, 39, who starred in last year's Mega Shark Versus Giant Octopus, will play an animal rights campaigner who frees exotic snakes from pet stores, allowing them to grow to mega sizes in the Everglades. Tiffany, 38, who starred in Mega Piranha, will portray a park ranger trying to save endangered alligators.

Wait — it gets better: They get into a fight in a swamp.

"I know that pop culture fanatics have been dying for Tiffany and me to collaborate for the past 24 years!" Gibson said in a statement. "What better way to do it than by battling each other in a campy romp through the Everglades?"

Added Tiffany: "Only in my dreams have I been able to have a catfight with Debbie Gibson...until now! This is soo MEGA Cool!"
