John Cena and Amy Schumer's movie "Trainwreck" is making headlines as the commediene dished out on their sex scene in the film.

In an interview in Australia's The Project talk show with co-star Bill Hader, Amy jokingly said that John allegedly forgot that he was acting during their bed scene.

"He was actually inside me. Apparently wrestlers, they're not faking!" Amy Schumer said, as quoted by Hollywood Life.

Bill Hader quickly jumped in to Amy Schumer's joke.

"He didn't understand the whole acting thing, it was his first sex scene," Amy's comedic partner-in-crime Bill Hader said.

John Cena on the other hand, admitted that the scene was a bit awkward.

"Yeah, it was uncomfortable. I never thought I would get the part in the first place," John Cena told FOX411 about his sex scene with Amy Schumer

"Then I got the part and was thinking I have to be naked. It was nerve racking. Amy was fantastic. Everyone embraced the comedy. Nicole had every right to be upset because I didn't tell her about it at first. I never really approached her with 'I'm trying to do this thing.'"

One person who was reportedly not amused by John Cena and Amy Schumer's sex scene? The WWE star's girlfriend and "Total Divas" star, Nikki Bella.

"Nicole had every right to be mad because I should have told her from the beginning. She's great. A relationship is based on communication. She knows I'm head over heels in love with her," John Cena said about Nikki Bella being jealous.

Nikki Bella's jealousy about John Cena and Amy Schumer's sex scene was well publicized and reported in tabloids. The WWE star may relatively be a private person, but he admits that having his girlfriend on "Total Divas" has opened his life for public consumption.

"It is weird. When they came to us with the concept of 'Total Divas' it wasn't so accepted around [the WWE]," John Cena said.

"Those girls who chose to put their lives are some of the bravest. I wanted nothing but success for her."
