Hiddlestoners will have a meltdown when the new movie "Crimson Peak" hits theaters! Apparently, Tom Hiddleston will have a sex scene in Guillermo del Toro's upcoming vampire film and his co-star is keeping mum about who he's going to do it with!

His co-star Jessica Chastain spilled the beans during an interview with MTV News for her movie, "A Most Violent Year.""Crimson Peak" was reportedly filmed simultaneously with the said movie.

According to the brunette beauty, the Internet's darling will be getting some bedroom action in the new movie.

MTV News reported that Chastain's "A Most Violent Year" co-star Oscar Isaac asked the actress what the yet-to-be-released film will make him feel "in [his] pants."

"In your pants?" she countered. "Well, there is a Tom Hiddleston sex scene, boys! I know!"

Of course the obvious follow up question would be who this mystery (and lucky) person could be. Chastain, however, was done teasing by that point.

"Not gonna say who, but there is some, you know. You can calm down," she casually told MTV's Josh Harowitz and her co-star Oscar Isaac.

According to Fashion & Style, the most likely candidate to be Tom Hiddleston's sex scene partner would be his onscreen wife, Mia Wasikowska ("Alice In Wonderland").

The synopsis of "Crimson Peak" suggests that Hiddleston, as Sir Thomas Sharp, will charm Edith Cushing (Wasikowska) into marrying him. When he takes her back to his ancestral home, however, she discovers "a jealous sister (Chastain) and more than a few skeletons in the closet."

While "The Help" star may have veered suspicions away from herself with her comment, Fashion & Style thinks that she could also be a good candidate, suggesting that her character may feel more than just brotherly love for Hiddleston.

"Crimson Peak" will be hitting cinemas in the US on Oct. 16 this year.
