'Bones' Season 9 Spoilers: Mckayla Maroney to Guest Star

Fans of Fox's hit drama "Bones" are in for a treat with tonight's all new episode. Olympic Gold Medalist McKayla Maroney will be guest starring.

Maroney will be playing the role of a gymnast named Ellie. But their athletic careers are where Maroney and Ellie's similarities end. Ellie is a suspect in a murder case in which her main rival is killed.

Maroney recently sat down with TV Guide to discuss her upcoming role. She talked about her audition, she was apparently sick but still landed the role.

"I had strep throat when I went in. I didn't know my lines or anything! I kind of just winged it. I honestly had no idea how I did. ... So when I got the part, I was so excited," the gold medalist said.

Maroney also said that fans will not be seeing her doing much gymnastics during the episode.

"I probably would've done some vaulting, but they didn't have any set up for the level that I am. They were all for younger gymnasts. It's more acting-based. I had to do gymnastics, like I did a round of handspring layouts, which I do every day in the gym and isn't hard for me to do," she said.

"But it was very hard for me to be ready to do gymnastics and then be ready to act. I would do a tumbling pass and then have to talk. But that's how it's supposed to be, like I'm in the gym and it's OK if I'm out of breath. It was an amazing experience. I had so much fun. Everyone was so nice," she added.

"Bones" airs on Fox, Fridays at 8/7c.
