Diane Kruger - Personal Hairdresser Diane Kruger

Diane Kruger cuts her boyfriend Joshua Jackson's hair.

The 'Inglourious Basterds' actress - who has been dating the former 'Dawson's Creek' actor since 2006 - admits she often gives his locks a trim at home, so as not to destroy his television-watching routines.

She said: "I cut Josh's hair all the time. He loves it because he can watch TV. I've only messed it up once, when he was moving around."

The 34-year-old actress has also revealed she sold her car so she could spend more time riding her bike.

She explained: "I'm an outdoorsy person, I love to hike and I sold my car - I have a bicycle. I'm not big on going to the gym, but I've always pretty much been the same weight. I don't ever weight myself, but you know when your jeans start feeling a little tighter? Then I have yoghurt and muesli days."

Diane also revealed she doesn't wear deodorant - but uses perfume to stay smelling fresh.

She added to InStyle magazine: "I'm allergic to deodorants, so I spritz scent under my armpits! Then wrists, then one little spritz here on my decolletage. Josh has only known me to wear one other fragrance and now Calvin Klein Beauty. I had to 'boyfriend' test" it - he approved."
