Twihards aren't the only people who find Robert Pattinson endearing. As Kristen Stewart proved, actresses can be equally impressed by the actor.

Bonnie & Clyde's Holliday Grainger recently opened up about her former Bel Ami and The Bad Mother's Handbook costar, revealing the deep respect she has for the British actor.

''I've known him since his pre-Twilight days when he was a normal person and it was still like, 'ooh you're playing Cederic Diggory (in Harry Potter And The Goblet Of Fire),' Grainger recalled of Pattinson before he rocketed to fame, according to Grazia Daily. "He's managed to keep very level headed and normal. I don't understand how."

When Pattinson suddenly found himself the mutual idol of teenage girls everywhere following the premiere of Twilight in 2008, Grainger watched him take it all in stride.

"I can't fathom the idea of living a life like he lives," the 25-year-old actress explained. "On the set of Bel Ami in Budpest there would be hundreds of screaming girls there at 5am and they would still be cordoned off when we finished. He had to move hotels because there were so many people outside his. One day he was signing autographs on the way home from work at 6am after a night shoot. Bless him, that's an extra level of hard."

Pattinson is currently filming abroad once more, this time in Morocco for queen of the Desert.
