Finally, an answer to the age-old question why Robert Pattinson smells. According to his “New Moon” co-star, Peter Facinelli, the heartthrob deliberately wants to smell to ward off the paparazzi.

Facinelli, who plays Pattinson’s adoptive father in the film, explains to New York Magazine why the 23-year-old star sports a body odor.

He said that he advised his screen son to not change his clothes. That way, when the paparazzi get his pictures in the same outfit all the time, then they won’t be able to sell the pictures because it will look like they were from the same batch.

Co-star Ashley Greene, who plays his sister Alice, tries to avoid breathing when he’s around, jokingly saying, out of a “defense mechanism, I don’t sniff him.”
