Brad Pitt has been studying Scottish castles.

The 'Inglourious Basterds' star spent time in Scotland last year, scouting locations in the Highlands for an upcoming film project with 'Kick-Ass' director Matthew Vaughn.

He said: "Last year Matthew and I were looking at doing some filming up there. We had a look at some castles. We'll definitely be back."

Brad - who raises six children with partner Angelina Jolie - has been a fan of Scotland for some time, but had to cut his last trip to the country short after he began feeling threatened by the former lover of his then-girlfriend.

He told The Sun newspaper: "I went to Scotland and travelled around years ago. I went everywhere, saw it all. Edinburgh and Glasgow were special - the architecture is something there.

"When I was in Glasgow I got involved with this girl. She happened to be the ex-girlfriend of a bit of a bad guy. I ended up having to get out of town because I was getting 'that' look from a guy behind a bar."

Brad also confessed a love for British rapper Dizzee Rascal and admits he exercises to his songs.

He said: "That guy has got it. The kids are really into this stuff. I have worked out to that song 'Bonkers'."
