As is often the case in today's world of increasing multi-hyphenate celebrities, once a singer enjoys chart success, speculation starts to be mount on when they'll make the leap into movies.

Justin Bieber is the latest star believed to be eyeing a potential screen project, but he is reportedly holding out until a scene featuring his character having sex with another man is written out.

Writer Pete O'Neill told the New York Post's Richard Johnson that the 22-year-old hitmaker has been offered the role of a pop star in Uber Girl, but won't sign on until it undergoes a 'major rewrite'.

That's not how he roles: Justin Bieber has reportedly refused to take on a role in the movie Uber Girl until his character's sex scene with another man is written out of the script

'He won’t take the part unless the sex scene with him and one of the male backup dancers is taken out of the final script,' Pete, who is co-writer on the coming-of-age project, told the publication.

Pete added that he hopes to land a starry cast for the project, currently in need of studio backing, that would include Justin's ex Selena Gomez, Ariana Grande and Mad Men's Kiernan Shipka.

MailOnline has contacted a representative for Justin Bieber for comment.

A real stretch: If he did take on the role, the 22-year-old Canadian singer would be playing a pop star

The singer's movie roles have so far consisted mainly of him starring in his own concert videos and making appearances in those of other artists, including Katy Perry and Zendaya.

As well playing a prisoner in two episodes of TV drama CSI: Crime Scene Investigation in 2010 and 2011, he also made a cameo appearance in Ben Stiller's Zoolander No. 2.

In real life, the star's bedroom skills were sized up by 30-year-old former Big Brother contestant Laura Carter, who said that she preferred the performance of Marco Pierre White Jr, 21.

The ex factor: A writer on the project would also like to cast Justin's ex Selena Gomez in the project

The recently-ousted contestant enjoyed a threesome with Canadian singer Justin last year before romping with Marco on the reality TV show - and says she had more 'sexual chemistry' with Marco.

Speaking to the Daily Star Sunday, Laura said: 'I've got to say that Marco is the better kisser. Marco is so hot. And we did have so much sexual chemistry. We really, really did.

'I think Marco and Justin are both the same age - they're about 21. I'm such a cougar. I'm not saying there wasn't sexual chemistry with Justin. I mean, he's Justin Bieber and he is really hot.'
