"Eddie is a horndog," Lambert told ET. "He's nasty."

Joining Lambert is Laverne Cox, Victoria Justice, Ryan McCartan, Annaleigh Ashford and Christina Milian.

"I'm starring in it, so it has to be really sexy," said Cox, who stars as Dr. Frank-N-Furter, originally played by Tim Curry. "The scale of the production is so huge. It's top-notch."

The two-hour television event follows a young couple whose car troubles lead them to stumble upon an annual Transylvanian science convention held by Dr. Frank-N-Furter.

Justice and McCartan play the two sweethearts originally depicted by a young Susan Sarandon and Barry Bostwick. Actor and singer Staz Nair plays Rocky Horror, the muscle-bound specimen created by Dr. Frank-N-Furter.

"This is the only industry where my job interview requires me to come in my boxers and dance," Nair pointed out.

The Rocky Horror Picture Show premieres Oct. 20 on Fox.
