The world's most famous street artist recently opened an interactive exhibition at a hotel in Bethlehem.
But a witness claimed she filmed him days before at an art show at a shopping mall curated by his former manager in nearby Israel.
The footage was snapped on a mobile phone, showing a man wearing a bucket hat and camouflage trousers.
He was filmed walking around an art studio carrying a stencil before looking at the camera and putting up a hand to cover his face.
But is it him?! More will be revealed soon I guess.
