Mila Kunis And Ashton Kutcher In Public Display Of Affection Shocker

It's not often that you see celebrities canoodling in public unless you're talking Tom Cruise and Katie Holmes circa 2010, but Mila Kunis just couldn't resist indulging in a spot of PDA at the new Gemfields campaign launch, supported by Ketel One Vodka, at the exclusive Phillip's Gallery in London on Thursday.

In a super-rare appearance, Ashton Kutcher supported his girlf at the event and was spotted admiring Mila - dressed in a black Antonio Berardi tuxedo with poker straight locks - along with the rest of the crowds (*sigh*) as she was introduced by Gemfields CEO Ian Harebottle.

While Mila took to the stage, the gloves were off and a flock of girls including Made In Chelsea's Ashley James had Ashton surrounded. As the MIC newbie started chatting away to Ash, Mila slinked off stage and cheekily pinched her boy's bum (RATHER!) before leading him away from the no doubt disappointed girls.

The party came as Ashton and soon-to-be-ex-wife Demi Moore finally got down to their nitty gritty divorce proceedings, with a settlement expected to be reached this Spring.
