Angelina Jolie insists that she loves every aspect of motherhood – including the painful birth part.

The mom-of-four - who is expecting twins with partner Brad Pitt – says she finds childbirth so “fascinating” that it outweighs any pain she may feel during the process.

"I had a C-section (with Shiloh) and I found it fascinating. I didn't find it a sacrifice and I didn't find it a painful experience," she tells the new issue of Vanity Fair.

"I found it a fascinating miracle of what a body can do."

Jolie and Pitt are also parents to adopted kids Maddox, six, Pax, four, and Zahara, three.
