Angelina Jolie has posed nude for a set of pregnancy paintings.

The Tomb Raider actress commissioned US artist Don Bachardy to paint three portraits of her to celebrate the different stages of her pregnancy.

However, the revealing paintings may never been seen by the public and instead are likely to remain in Angelina's private collection.

A source said: "Angelina has asked him not to talk about or show the portraits to anyone."

Bachardy - who has also painted Hollywood legends Rita Hayworth, Jack Nicholson and Bette Davis - flew to Paris and Namibia to paint the Mr & Mrs Smith actress before she gave birth to daughter Shiloh Nouvel last month.

Meanwhile, Angelina made an emotional trip to Los Angeles so Shiloh Nouvel could meet her dying grandmother.

Angelina's mother Marcheline Bertrand has terminal cancer and was too ill to fly to Namibia for the birth.
