Cathedral volunteers can't ''make eye contact'' with Mila Kunis on set.

The 29-year-old beauty is shooting scenes for 'Jupiter Ascending' at Britain's Ely Cathedral and workers at the place of worship have been urged to not disturb the actress or her co-star Channing Tatum.

An insider told the Daily Mirror newspaper: ''Staff and volunteers at the cathedral have each received a memo instructing them not to bother the stars, or even make eye contact.

''It is a real coup for Ely having someone like Mila filming and they realise how important it is to let her get on with her work without being bothered by overexcited choristers.''

Both the stars have been ''smuggled'' onto the set to avoid disturbing the regular goings-on of the cathedral, although a lot of the building itself has been closed down to avoid doing the same to the film.

The source added: ''She and Channing have been squirreled away, and they are being smuggled in so they cause as little bother and distraction as possible.

''Much of the cathedral has been closed down as well to ensure filming continues seamlessly.''
