"Of course I've lost weight. Some days are exhausting, only I'm not allowed to collapse," Ange told French magazine Gala. "I believe in pushing myself to the limits."

The actress, confirms her shock weight loss began following the death of her mother Marcheline Bertrand in January this year. In the months that followed, she says Brad guided her through the grieving process, even though she often shut him out.

"When my mother died, Brad helped me go through all the stages of handling what you have to deal with when someone dies," she says. "I recognize that there were times when he wanted me to open up, but sometimes it's difficult to do that."

While she credits Brad with helping her through her difficult times, the star admits much of the sexual passion has fizzled out of the couple's relationship as they struggle with the demands of parenthood and busy careers.

"Obviously your intimacy is not the same," she says. "You are always engrossed and often you collapse with exhaustion in the evening.

"But I am a very lucky woman. Brad is very romantic in his ways. And we talk deeply about how we feel about everything..."
