Cameron Diaz can't wait to babysit Drew Barrymore's daughters.

The 'Other Woman' star is planning to visit the 39-year-old actress and her children Olive, 19 months, and one-week-old Frankie, later this week, but she insists she'll soon be looking after the youngsters while Drew and her husband Will Kopelman enjoy a nice child-free night out.

Speaking to PEOPLE.com, Cameron said: "I haven't seen her [Frankie] yet but I'm going to this weekend. [Drew] is doing wonderful[ly]. Of course [I'll babysit], I'm an auntie!"

However, Drew recently admitted that she and Will prefer to care for their children without babysitters as they like to spend the weekends together as a family.

She said prior to Frankie's birth: "I am loving being a mum ... We spend every weekend together. We don't have a babysitter. It's just us. I can't wait to see how that's going to work out with the second one!"

Although, the blonde beauty may make an exception for her friend Cameron as they spent a lot of time together throughout her pregnancy at cookery lessons.

Drew said recently: "I really love cooking, it makes me so happy. But I'm terrible at it. None of it is effortless or sexy or even tastes that good for that matter, but I'm really working on it. I might travel somewhere to do it, and bring the family. I love cooking for Olive now, but I used to be Mrs Takeout.

"I've just never learned to cook in my life. Cameron's a great cook, and always has been. I'm just trying to catch up to that."
