Mila Kunis and Channing Tatum "got in trouble" for losing too much weight filming ‘Jupiter Ascending’.
The 31-year-old actress – who has two-month-old daughter Wyatt with fiancé Ashton Kutcher – admits the futuristic action adventure was the most physically demanding project she has ever undertaken and felt like a "massive boot camp".
She said: "The whole film was a massive boot camp. I have no body fat in this movie for the first time in my life.
"For five days a week, you train every single day, for six months. Just work out all day long for six months and yu too will have no body fat.
"We both got in trouble for losing too much weight. It was really bad."
Mila doesn’t think she is very much like her character Jupiter because she has always believed in herself and felt supported.
She told SFX magazine: "Even at my lowest when I was trying to figure my life out or going through puberty I never doubted myself like Jupiter did.
"I always had a very good backbone, being my family. Which was always an incredible support system.
"So anytime I questioned anything it was never as dire as Jupiter. I think Jupiter feels like she’s alone. I’ve always been very lucky where I never felt alone."
