Angelina Jolie's latest public appearance has fuelled rumours she is pregnant.

The Hollywood star was sporting what appeared to be a bump at an event aimed at helping children growing up in conflict zones.

She spoke at the event in Washington after visiting hot spots as a UN goodwill ambassador.

Jolie and partner Brad Pitt have not confirmed that she is expecting another child.

The couple already have four children, biological daughter Shiloh Nouvel Jolie-Pitt and three adopted kids.
