Robert Pattinson's New Moon co-star Alex Meraz has defended the actor against allegations he smells a bit off.

On-set sources were quoted as saying that the gloriously-haired actor has been stinking up filming on the Twilight sequel because he doesn't shower.

Rob denied this and pointed out that he hadn't actually set foot on the Vancover set at the time.

And castmate Alex seconds this.

"He smells like roses!" he tells E!online.

"The first time I met him, I was like, 'Dude, you smell fantastic!' I don't know where people get this stuff from."

Probably from people like the fan who spotted a dishevelled Rob at Los Angeles airport on Monday: "I was so disappointed. Rob's hair was a mess, he was so skinny and he was chewing his fingernails."

No word yet on his aroma...
