"Angelina has decided she would like a more shapely figure when she weds Brad and is hoping to gain 10 pounds. Brad and Angelina have asked Jamie to suggest some recipe ideas for them," said a source.
Pitt is also keen that Jolie puts on some pounds as he prefers her curvier figure.
"Brad would love her to have curves like she did when they met on 2004 movie Mr and Mrs Smith. Jamie has been to Brad and Angelina's home numerous times. They have a similar sense of humour and are all down to earth," the source said.
