It's going to be a busy few years for Grease fans.

The 1978 musical currently has two prequels in the works, and up first is TV series Grease: Rise of the Pink Ladies, coming in 2021. It will focus on how "Sandy, Rizzo, Jan, Marty and Frenchy came together and how the reverence, fear and moral panic they sparked changed Rydell [High School] forever," according to THR.

Grease star Olivia Newton-John on new Pink Ladies TV show

Olivia Newton-John — "Sandy" to John Travolta's "Danny" in Grease — spoke on Rise of the Pink Ladies while on Watch What Happens Live with Andy Cohen. Fittingly, the host ran her through a "Greased Lightning Round" of questions, including pressing for an honest reaction to the new prequel.

"I'm very curious what they're gonna do, I can't imagine what they're gonna do," Newton-John replied. "But I think Grease is so loved and beloved, which is amazing, that I think people will be curious," she added. "I'll be curious to see what they come up with."

Cohen also asked Newton-John to reflect on the Grease premiere, in 1978, a famously star-studded and wild night. "Oh gosh, I just remember it was crazy," the actress recalled. "There were lots of people in the bathrooms doing strange things that I hadn’t seen before," she laughed. "It was wild and fun, a very exciting night."

Grease: New TV prequel and movie in the works

If you've been following the Grease prequel news, Rise of the Pink Ladies was originally titled Rydell High and going to be an HBO Max production. But earlier this month, it moved to Paramount+ (currently known as CBS All Access) and refocused to a Pink Ladies origin story.

In addition to Rise of the Pink Ladies, a prequel film, Summer Lovin', is in the works, said to focus on the meeting between "Danny" and "Sandy" referenced in the musical's "Summer Nights" song. If you're as curious as Olivia Newton-John is, stay tuned for more on the upcoming Grease prequels.
