Bottom’s up! Jennifer Aniston get dumped in a car boot by her prankster co-star Gerard Butler.

The grinning actress, 40, thought he was just giving her a hug on the set of their latest movie, The Bounty.

Instead the Scots hunk, 39, scooped her up and popped her into the trunk of a nearby limo.

A New York studio source said: “Jen and Gerard have a real chemistry and are always mucking around.

“Luckily she managed to see the funny side.”
