Suki Waterhouse was ''amazed'' by Bradley Cooper's level of intelligence when she first met him.

The 22-year-old British model has been dating the 'American Hustle' star since last February, but it wasn't just his hunky looks and suave personality that caught her eye, as she was also captured by his passion for reading and his ability to speak fluently in French.

A source told RadarOnline: ''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.''

Meanwhile, the blonde beauty is reportedly hoping Bradley, 39 - who married actress Jennifer Esposito in 2006 before divorcing her in 2007 - will propose to her in the near future.

The source explained: ''There's a big age difference between them, but Suki adores Brad and after winning over his mum's heart she's hoping for a ring on her finger.

''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.''
