Angelina Jolie may be trying to get pregnant with twins after reportedly undergoing IVF to have more children with fiancé Brad Pitt.

Hollywood Life reports that Jolie wants to give birth to more children before it's too late.

The report comes just months after Jolie revealed that she underwent a double mastectomy as a preventative measure against developing cancer for the sake of her family.

The power couple have been together for eight years and currently share six children together – twins Vivienne and Knox, 5, Shiloh, 7, Zahara, 9, Pax, 9, and Maddox, 11.

The insider told Hollywood Life: "Angelina and Brad are dying to have more children. Twins would be ideal."

Jolie and Pitt clearly love having their hands full looking after their children and has made it no secret that they wanted to have more.

Jolie revealed on May 14 that she underwent a secret double mastectomy after learning that she was a carrier of the BRCA1 gene, which increased the chance of her getting breast cancer to 87 percent. She underwent three months of secret procedures starting February 2 and ending April 27.

The actress revealed that she had the procedure done for the sake of her own children, after her own mother, Marcheline Bertrand, passed away aged just 56 from ovarian cancer. The procedure reduced Jolie's chance of developing cancer to under 5 percent.

In a piece published by the New York Times titled "My Medical Choice" , Jolie wrote: ''I am fortunate to have a partner, Brad Pitt, who is so loving and supportive. So to anyone who has a wife or girlfriend going through this, know that you are a very important part of the transition. Brad was at the Pink Lotus Breast Center, where I was treated, for every minute of the surgeries.We managed to find moments to laugh together. We knew this was the right thing to do for our family and that it would bring us closer. And it has."

Pitt revealed that he was proud of Jolie, in a statement released to The Evening Standard. "Having witnessed this decision firsthand, I find Angie's choice, as well as so many others like her, absolutely heroic. I thank our medical team for their care and focus. All I want for is for her to have a long and healthy life, with myself and our children. This is a happy day for our family."

Jolie wrote: "My chances of developing breast cancer have dropped from 87% to under 5%. I can tell my children that they don't need to fear they will lose me to breast cancer."
