But, we were slightly put off when we found out Robert, who plays vampire Edward Cullen in Twilight, never changes what he wears - or washes. Grim.
Robert says he loves shopping in charity shops, but says being followed everywhere by drooling girls makes it difficult to expand his wardrobe.
He says: "I like second hand. But I can't really go into second hand stores to get new clothes any more so I end up wearing the same thing every day.
"I wish I could shop in vintage stores the whole time. But because a lot of paparazzi follow me around, it can be difficult."
So Robert - who is dating his 'Twilight Saga' co-star Kristen Stewart - turns to designer Marc Jacobs.
He added: "At almost every single premiere I wear Marc Jacobs. It seems to be the only stuff that fits me."
It has previously been claimed that the British star rarely showers.
A source close to the star - who plays vampire Edward Cullen in the film franchise - previously said: "He stinks. I mean, it's awful. He never showers, and it drives people on the set crazy. He completely reeks."
To paraphrase EastEnders, sort it aaaaaaaht Kristen! (source)
