What better way to celebrate your engagement than by asking your future wife-to-be to appear on your own sitcom? A CLASSIC move - obviously. Mila Kunis joined the cast of Two and a Half Men recently for a guest role, where she plays a world traveller, who Ashton Kutcher's character Waldon, takes quite a shine to.

The full episode will be broadcast in America on Thursday, but below is the first preview;
