Amy Schumer’s joking about a s** scene in her new film Trainwreck, in which she shares a bed with wrestler John Cena, has got Twitter in stitches.

The American comedian, who is now in Australia promoting her new film, quipped on Tuesday that her co-star, professional wrestler John Cena, had forgotten he was meant to be acting in the s** scene.

Fifi Box from The Project’s panel prompted Schumer to discuss the s** scene in their film while she was on the show with her movie co-star Bill Hader.

“That intimate scene with you in the bedroom, Amy..,” Box began.

Hader cut them off before they could continue, saying:

“The s** scene? That was so sweet of you! The scene in the bedroom where you’re intimate, on top of each other.”

Schumer said when asked how many takes it took to shoot the sequence and how she kept a straight face during it: “Because he was actually inside me. Who am I to stop him?”

‘He didn’t understand the whole acting thing,’ pipped in her comedic partner-in-crime Bill Hader, ‘it was his first s** scene.’

‘Apparently wrestlers, they’re not faking!’

The Project’s Peter Helliar continued to interview her, saying “Inside your apartment, that’s what where…” before Schumer interrupted again.

She responded, “It’s alright if you want to call my v@gina my apartment.”

“I’m not from here. I don’t know what you guys…”

“Yeah, is that what they call it here?” Hader interjected again.

Okay, now relax. Schumer was most likely, completely, perhaps, and hopefully kidding. Before a conventional Hollywood movie production can accidently become a p*rn set, a lot of precautions have to fail. For the sake of my own sanity, I’ll presume Cena didn’t really Rise Above his cock sock.

In the film, the comedian, who has dated fellow wrestler Dolph Ziggler, has a brief s** scene with John in which she requests that he talk dirty to her.

‘I was coming out of the gym, I’d just done a huge squat workout, had those short shorts on, my legs were throbbing…’ he says.

‘Ok, you’re just describing yourself,’ Amy responds, unimpressed, before the two reach climactic heights.

Still, you have to wonder what Nikki Bella thinks of Amy’s fun penetration repartee and nonstop coverage of her (common law) husband’s s** scene. Cena discussed how he told Nikki he’d be having a s** scene with another lady in a Fox News interview. Or, more particularly, how he failed to inform her.

“Yeah, it was uncomfortable. I never thought I would get the part in the first place. 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.’ Nicole had every right to be mad because I should have told her from the beginning.”
