Kristin Chenoweth may not be starring in 'Fifty Shades of Grey,' but she is dating the producer, Dana Brunetti. And therefore, she has the on-set scoop.

"They're really, really salacious and wonderful," the 45-year-old former 'Wicked' star told E! about stars Dakota Johnson and Jamie Dornan. "It's an easy read and fun. I think that Dakota and Jamie, I met them both — I didn't see their work because it's a closed set, but I do see how they both got the parts — could not have been lovelier."

"That always helps," she added. "'You're talented and you're nice?' Fantastic!"

While the cast couldn't be friendlier, the provocative film (based on the series of erotic novels) has raised some eyebrows. Specifically, the eyebrows of Chenoweth's mom.

When the 'Glee' actress took Brunetti home to visit her parents in Oklahoma, the producer -- who has also produced 'House of Cards' and 'Captain Phillips' -- was given the third degree.

"My mom's like, 'Are you doing porn?'" Chenoweth imitates in a Southern accent. "Is that 'Fifty Shades of Grey' porn?' I'm like, 'Stop talking, mom! Quiet.'"

But don't worry, Mom -- as raunchy as 'Fifty Shades' may be, it's not too hardcore. Brunetti tried to explain this to Chenoweth's mom.

"He's like, 'Not really, Mrs. Chenoweth,'" the actress recalled. And the petite starlet agrees: "I think it's going to be done very, very tasteful."

We can't wait to find out!
