Robert Pattinson is rumoured to be worried about his possible girlfriend Kristen Stewart because she has to shoot some rather up close and personal sex scenes for her new movie On The Road.
The actor is believed to be so concerned that he will be on set for Stewart that he is reportedly going to spend his time on set to make sure that everything is above board.
A source told Hollywood Life: "Rob plans on being on the set of On the Road, not because he has a role in the drama, but because Kristen has a real risque part!
"There are a lot of sex scenes including a threesome, and Rob wants to make sure that it's all pretend from the start and finish of the film."
"He's very jealous. Kristen told him she didn't want him on the set because it would make her feel uncomfortable, but Rob said he's going to be there.
"Especially now that her scenes are with Viggo, who is very. very hot! Rob is free until filming begins on the next Twilight film, so he's got all the time in the world to keep an eye on Kristen - and he will."
The On The Road sees Stewart working alongside Sam Riley, Garret Hedlund, Kristen Dunst, Amy Adams and Viggo Mortenseon in the Walter Salles directed movie.
On The Road is just one of three projects that Stewart has on the go with Twilight Saga: Breaking Dawn and K-11 also in the pipeline.
