Robert Pattinson and Kristen Stewart's real-life chemistry may make on-screen love scenes less awkward to perform, but Pattinson has revealed that some episodes of their Twilight romance were scary.

Citing a scene in the Twilight Saga: Breaking Dawn-Part 1, where the couple break the bed in a sex scene, Pattinson said he was seriously distracted by the cue, according to Celebrity Dirty Laundry.

I've never done a sex scene where it's kind of scary because you think something is going to fall on you! There was a whole stunt set up with three guys, who do all the explosions and things, all lying under the bed. I spent the whole time looking at them for a signal. It was funny, though, the 25-year-old allegedly told the gossip magazine.

Stewart was recently spotted donning Pattinson's T-shirt at the 2012 WonderCon, where she was promoting her new film, Snow White and the Huntsman. Pattinson was seen wearing the same T-shirt on the set of Cosmopolis.

Bel Ami U.S. Premiere Announced

Meanwhile,Robert Pattinson's highly anticipated Bel Ami will premiere in the U.S. on June 8, Magnolia Pictures said last Wednesday.

The company will be releasing the film on demand a month before it debuts in U.S. theaters, anticipating that it will not do as well on big screens over the summer, according to All Voices.

The film premiered at the Berlin Film Festival last month and will premiere in Lithuania, France and the UK before it hits the U.S. box office.

Pattinson plays a young man in 19th century Paris who manipulates influential and wealthy women (not including Kristen Stewart) to rise to power.

Pattinson's on-screen love interests include Christina Ricci, Uma Thurman and Kristin Scott Thomas. In a recent red-carpet interview at the Berlin Film Festival, the Twilight star referred to his love-making scenes as getting his cake and eating it too, according

Pattinson told Hollywood Life the women in the Bel Ami cast all played very strong characters. So it wasn't like I could push them around easily. It was funny. I had to be a different person with all three of them, he said at the Berlin Film Festival.

He told that his favorite part of playing the promiscuous Georges Duroy was being able to manipulate and romance women of varying ages. Hmmm older women or younger women...I get my cake and eat it, too, basically. They both have their good sides, he said.

Christina Ricci, however, complained about the nature of her character, calling the experience of acting intimate and romantic with so many crew members a horror.

Bel Ami, is based on the novel by Guy de Maupassant, capturing the social conflicts of the 19th century, through a sharp focus on lusty affairs carried out by a Parisian lawyer, played by Pattinson.
