Brangelina 'thrilled to be adding to their brood'

Washington, Feb 24 : Rumours of Angelina Jolie being pregnant with twins have become more realistic after a source revealed that the actress and partner Brad Pitt are 'thrilled to be adding to their brood.'

The actress had recently set the treadmills running when she was seen with her baby bump in a curve-hugging black dress at the Film Independent's Spirit Awards with Pitt.

"They are very, very happy," People quoted the source, as saying.

The 'Mr. and Mrs. Smith' pair already has 4 kids in their family, Maddox, 6, Pax, 4, Zahara, 3, and Shiloh, 1.

In fact, the couple's adoption of Pax was made official only last week.
