Angelina Jolie reportedly wants to gain 4.5kg before her wedding.

The actress — who has drawn criticism in recent times for her increasingly slender frames — is set to tie the knot with Brad Pitt this summer and is keen to put on a bit of weight as she wants some curves to fill out her dress.

So she and Pitt — who raise six children together — have reportedly asked British chef Jamie Oliver to give her recipes for hearty yet healthy meals.

A source told the Daily Star: "Angelina has decided she'd like a more shapely figure when she weds Brad and is hoping to gain ten pounds. Brad and Ange have asked Jamie to suggest some recipe ideas for them.

"Ange never cooks so Brad's now knocking up some English dishes like shepherd's pie and sausage and mash."

Pitt — who was previously married to Jennifer Aniston — is also keen for Angelina to gain a few pounds as he prefers her when she has a curvier figure.

The source continued: "Brad would love her to have curves like she did when they met on Mr and Mrs Smith in 2004.

"Jamie has been to Brad and Ange's home numerous times. They have a similar sense of humour and are all down to earth."
