Mila Kunis is reportedly set to make a guest appearance in her fiancé Ashton Kutcher's sitcom Two And A Half Men.

The sultry star, 30, will play a woman called Vivian who turns up on the doorstep of Kutcher's character Walden.

The Hollywood Reporter describes her as "a young, beautiful and free-spirited world traveller".

And the report explains that: "Walden feels an instant connection with her, convinced she's 'the one'. The problem is, Walden was about to propose to someone else."

Kunis and Kutcher were widely reported last week to have got engaged - and were snapped sharing a PDA at a basketball game yesterday.

The couple are a regular sight at the LA Lakers' home games and repeated their recent trick of covering their faces as they obliged the kiss cam.

Mila held her black-fingernailed hands in front of their mouths as they snogged in front of thousands of fans.
