Canadian pop star Justin Bieber has done some pretty crazy things in the past but there appears to be something he's drawing the line against - a sex scene with a guy in an upcoming movie.

Just recently, Bieber was offered a role in a new movie called "Uber Girl," which is described as a coming-of-age film. Bieber is all for being a part of the film, but he is reported to be demanding a major rewrite in one particular scene.

"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," co-writer Pete O'Neill tells Page Six.

Aside from Bieber, other singers who are being courted to appear in "Uber Girl" include Bieber's ex-girlfriend Selena Gomez and Ariana Grande. Kiernan Shipka, who plays Sally Draper in "Mad Men," has also been offered a role.

Bieber earlier confessed that he faces a lot of challenges in strengthening his relationship with God. On his Instagram account (@justinbieber), the singer posted a photo which reads, "I don't always feel God's presence, I feel it may be human distractions or maybe I'm letting lies [keep] me from accessing it. Regardless, it doesn't stop me from seeking. Although it is frustrating, I'm reminded that relationships take work, even with God!"

He then posted another photo that he captioned, "I'd rather be lonely than to hang out with just anyone to not feel lonely. They have to be awesome or I'm Netflix and chill."

Bieber was not yet through with his reflections. A week later, he posted yet another message voicing his inner thought. "It's crazy how some people don't even question or ponder the reason for their existence and are okay going through the motions. We don't live to die. We have purpose and meaning!" he wrote.
