Celebrity baby names: Willow
'I grew up near one. It is the most flexible tree and nothing can break it: no wind, no elements. It can bend and withstand anything. I love that sentiment and I want that for her,' she told HELLO! magazine.
'Sage is cleansing and sacred and it sounds great with Willow,' she added. 'It doesn't hurt that her last name is Hart - flexible, cleansed heart.'
In December 2016, they added to their family again with son Jameson Moon.
Actor Will Smith and his wife Jada also have a daughter named Willow.
