Hollywood's A-list couple Brad Pitt and Angelina Jolie may cancel their long pending wedding plans as rumour suggests that Jolie is pregnant with twins.

According to the popular US tabloid Star magazine, the couple is expecting their twins but fears that the wedding cancellation would disappoint their other kids, gossip website reported.

Brangelina are the biological parents of three children, Shiloh, Knox, and Vivienne and have three adopted children, Maddox, Pax, Zahara.

Jolie has been recently in the news after her makeup went horribly wrong during the premiere of her movie Maleficent.

However, in spite of the pregnancy, the Maleficent Star has decided to go on with her wedding as they are planning their summer wedding.

"Brad and Angie have decided to just go ahead with the wedding, even though she is pregnant, mainly because they know postponing it would disappoint the kids. Angie couldn't care less about having a baby bump under her dress. And a summer wedding was something they were always planning on," a source close to the stars told the US tabloid.

As per the tabloid, Joile had gone through IVF treatment in order to get pregnant with twins, the website reported.

"When [Brad and Angie] had the eggs implanted, Angelina and Brad were warned it might not take, so they didn't get their hopes up.

"They didn't even tell their kids about it, because they knew how high the chance of disappointment was. But the IVF worked, and now she's pregnant. Angie is so happy about it, she's already calling this her 'miracle baby,'" the source added.

While fans are still guessing about the wedding date and theme of Branjelina, Marie Claire UK reported that the wedding might happen on a boat as per the star couple's children's wishes.
