But the Oscar-winning mother-to-be said that she has been trying to follow the advice of her make-up artists and experiment with bolder styles.
She told InStyle, 'I feel like a clown if I put on strong lipstick, but recently I've experimented with reds. Make-up artists have been urging me to try stronger lips, but it still doesn't feel like me. I'm working on it.'
The 29-year-old added that she also needs help to tame her 'triangle' hair.
She explained, 'When you see me, a professional has done my hair - I don't know how to. As a family, we have very curly 'Jewish' hair, when it's long it comes out in a triangle.'
