Drew Barrymore has been given the ultimate praise as a new mum - her mother-in-law insists she's the greatest parent.

The actress is mum to 19-month-old Olive and Frankie, who was born last month (Apr14), and Coco Kopelman can't believe what a great job she does juggling work commitments with her duties as a mum.

Kopelman tells Life & Style magazine, "She is the quintessential mother. With the new baby, she's very delicate. With Olive, she makes her laugh... she clowns around with her on the floor. She's a real entertainer, which is what she's done all her life."

And Coco is a very proud grandmother too, adding Olive is "very affectionate".

She says, "She loves to pat Frankie on the head. It's very cute! It's exactly what you want for two little girls who are 19 months apart."
