Kellan Lutz has a "nudity clause" whenever he takes on an acting job.
The 32-year-old actor has insisted he'll never strip his clothes off for his career, as he doesn't believe it is necessary for creating a scene, and has implemented a clause in his contracts which prevents directors from asking him to take his kit off.
He said: "I have a nudity clause. I just don't think nudity needs to happen. For me, I don't need to walk out of a shower showing my ass.
"God gave me this body. He gave me the genetics. He gave me the ability to work out. He gave me the drive to do what I do, so I'm going to do it until he takes me out of it."
The 'Twilight' actor also admits a large part of his decision to keep his clothes on is due to "boundaries" he has set with his fiancée Brittany Gonzales, as he knows it can be upsetting for a partner to see their other half in steamy romantic scenes.
He added to TV show 'Extra': "And I also have boundaries for myself and my fiancée. I have dated actresses. Seeing them making out with other guys or sex scenes, it kills my heart. And if that makes you a brilliant actor and win awards - I don't want awards."
Whilst Kellan and Brittany might have an established boundary, the star didn't have the same rule in place when his previous flame Brittny Ward posed nude for Playboy magazine when she was named the Miss January 2015 Playmate.
The 'Legend of Hercules' star popped the question to Brittany earlier this year, and news of the engagement broke after the beauty was spotted with a ring on her finger.
A source said: "A woman sitting outside having breakfast shouted Kellan's name and he walked over to her with Brittany. She was congratulating them and asked them if they were getting married in New York or L.A. They walked into the restaurant and when Brittany opened the door, I could see her large engagement ring!"
