Archaeologist Sienna Miller

Sienna Miller wanted to be an archaeologist when she was younger.

The stunning actress - who is rumoured to be romantically involved with married father-of-four Balthazar Getty - admits while acting was always her dream, she did consider a different career option.

She said: "I wanted to be an archaeologist. I'd probably have something to do with art or something, but to be honest I never really allow myself to think about anything else."

Sienna also revealed she finds it hard living up to her on-screen image in real life.

She added: "On screen, they light your body for hours so that you don't see every lump and bump and they spray your butt so it looks really nice, but it doesn't look like that in reality. You don't see all the stretch marks on film."

However, Sienna insists she is happy with the way she looks.

She explained to Britain's Look magazine: "I feel like I am fine with who I am and I'm fine with cellulite and I know it's normal. I'm not under any delusions of perfection and I don't feel glamorous at all."
