Will gazed adoringly at his wife, and planted a loving kiss on her lips, at the launch of her photography book during a party thrown in her honour by Chanel in New York.

Fittingly, Drew 's art project Find it in Everything is a homage to her lifelong love of hearts, the shape, and what it represents.
The pregnant star looked chic at the unveiling in a floor length black dress with side split and a matching blazer. She finished off the look with Chanel accessories, including a clutch bag, beaded necklace and cuff.
Drew is expecting her second baby with Will. The couple are already parents to baby Olive, who is one – and the expectant mum recently confirmed they are set to welcome a second little girl.
She subtly shared the news in December while talking about her "future daughter" when accepting a beauty award in celebration of women.
Drew's new book was released on Tuesday, and to mark the occasion the actress uploaded a cute Twitter pic of herself signing copies with some help from her pet dog.
The star says her obsession with hearts began while she was a little girl filming E.T.
"Hearts are my beacons. I love them man-made and natural, young and old. Whenever and wherever I see the heart shape, a smile spreads across my face," she says.
"The heart has an unbeatable romance when you discover one where you least expect it."
