John Cena
WWE superstar will appear almost naked in his upcoming movie Trainwreck Imgur

WWE superstar John Cena will appear almost naked in his upcoming comedy Trainwreck, which also stars stand up comedian Amy Schumer as the lead.

However, fans of the wrestler will not get to see his privates as Cena covered it with a fake one! And the star revealed this and more, when he appeared on Jimmy Kimmel Live.

"I have a 'big part' because of the costume department, I was gifted a stunt penis," the 37-year-old WWE star said on the show.

"I had to do a sex scene that involved me being almost all the way naked," Cena added. "I had to stuff myself in a small nylon sock and they gave me a stunt penis to insinuate an erection."

The Judd Apatow-directed comedy film is written by Schumer and the wrestler-turned-actor is playing the character of Steven, a self-obsessed hookup for Amy, according to Us Magazine.

The plot summary of the movie according to IMDB reads as follows:

Since she was a little girl, it's been drilled into Amy's head by her rascal of a dad that monogamy isn't realistic. Now a magazine writer, Amy lives by that credo - enjoying what she feels is an uninhibited life free from stifling, boring romantic commitment - but in actuality, she's kind of in a rut. When she finds herself starting to fall for the subject of the new article she's writing, a charming and successful sports doctor named Aaron Conners, Amy starts to wonder if other grown-ups, including this guy who really seems to like her, might be on to something.

The trailer of the film talks about awkward encounters between Steven and Amy. The movie is scheduled to release on 17 July this year.
