The 45-year-old actress, who has four-year-old daughter Valentina with husband François-Henri Pinault, said that having a laugh at herself helps her lighten up.
'If you're feeling blue, lock yourself in a room, stand in front of a mirror, and dance — and laugh at yourself and be sexy,' she told Redbook. 'Dance the silliest and ugliest you've ever danced.
“Make fun of yourself and try to recover your sense of humour. I do that with Valentina, especially if she's pouting, and it always works.'
Another go-to technique for putting a smile on her face is dressing up.
'I was having dinner with my friend Demi — yes, that one — and she said, 'Oh, my God! Every time I see you, you are so put together!' And I told her it's a lot easier to grab a fabulous little dress than to put together a whole casual outfit with jeans, a top, the right jacket, and great shoes. You slip on a dress and you can't go wrong.'
