ANGELINA JOLIE's adopted son MADDOX shocked crew members at a recent photo shoot in California - by calling BRAD PITT "Daddy".

Jolie and Pitt have repeatedly denied reports they are a couple, since Pitt and Aniston ended their five-year marriage in January (05).

But photographs of the couple travelling around Africa and Europe with Maddox have fuelled rumours they are secretly dating.

Pitt has always wanted to become a father, and has had such a powerful effect on Jolie's three-year-old, he now regards him as his dad, reports British newspaper The Sun.

A shocked witness says, "Maddox shouted, 'Where's my daddy? I can't see my daddy?'

"Crew members were truly taken aback that he was referring to Brad as 'Daddy'."
