The actor is very smart

Bradley Cooper‘s not just a good-looking movie star – he’s also a bit of a brainbox.

The American Hustle star, 39, has reportedly left girlfriend Suki Waterhouse stunned by his sharp mind and highbrow interests.

[Suki’s amazed] at how intelligent he is,’ a source says.

She was ready to write him off as another hunky dumb actor, but Bradley really surprised her with his fluency in French and the intense pile of reading material he has beside his bed.

He also always carries a backpack of very intellectual books with him to stave off boredom.’

British model Suki, 22, started dating Bradley last year and the two have seemed very loved-up of late, having attended several public events together.

And things appear to be getting pretty serious.

There’s a big age difference between them, but Suki adores Brad and after winning over his mom’s heart she’s hoping for a ring on her finger,’ the insider tells Radar Online.

He’s so different from the men she usually meets in the modelling world.

Suki loves that Brad’s smart as well as sexy. He can’t do anything wrong in her eyes.’
