Drew Barrymore is planning a sleepover with her daughters for her 50th birthday

Drew - who has Olive, 12, and Frankie, ten, with ex-husband Will Kopelman - told Us Weekly: "I've always spent the night with them on my birthday and their birthdays.

"We have a tradition, so I'm doing a night or two of sleepovers leading up, and then I'm doing a sleepover with my daughters on my 50th. ?But the whole theme of ?the 50th birthday is sleepovers. Sleepovers should never go away."

Drew actually feels happier and healthier than ever as she approaches her 50th birthday.

The actress - who first found fame as a child, starring in the 1982 sci-fi movie 'E.T. the Extra-Terrestrial' - shared: "I don't think I've ever known a happiness that I feel now, and I just didn't know I would ever get here."

Drew is also trying to strike the right balance in how she parents her children.

The actress is keen to give them some degree of freedom, but she also feels a responsibility to steer them in the right direction in life.

The 'Charlie's Angels' star - who was married to Will between 2012 and 2016 - explained: "They are who they are, and they're their own people.

"I'm not desperate to impose upon them at all who they should be, but sometimes I feel it's my responsibility to show them how to be and that there's just no room for not being kind to people or gracious or grateful.

"If I had one battle to choose, it would just be that they're kind, good, humble, grateful people and that they feel safe."
