Sadie Frost has described parenthood as a "confusing and "conflicting" time

She told OK! magazine: "One minute we're teenagers running riot, then we're in our 20s and doing whatever we're doing there. [laughs]

"Then you become a parent and you've got all this confusing, conflicting stuff because you don't know what you're doing.

"Then suddenly the kids are leaving home and you're like, 'Who the hell am I?' I've loved my life, but I've had four children and that's been full-on.

"Now I can do, 'Well, what do I want to do next? And how do I keep myself healthy and happy doing it?' You have to take care of yourself."

Sadie is also getting used to being a grandmother for the first time after son Finlay welcomed a baby girl into the world with wife Charlotte Mallory in December.

She pondered: "I think anybody that becomes a grandma struggles to identify with the new name.

"It can be like, 'Oh no, I'm suddenly going to turn into the grandma in Little Red Riding Hood and overnight I'll have a perm and glasses' - not that there's anything wrong with that.

"A lot of people don't call themselves granny or nanny, they have a pet name, and I chose Mimi. But weirdly, when I'm around my granddaughter, I say, 'Oh, Granny's here!' so that goes out the window."

However, Sadie hopes the nickname can become more of a thing when her granddaughter is a little older.

She added: "Maybe when she's older and we're in the park, it'll be nice if she calls me 'Mimi Sadie'. I think it's something that maybe feels weird at first but you're just so happy to be looking at this beautiful angel, you could be called anything."
