Mila Kunis and Ashton Kutcher are practically living together.

The couple have yet to confirm they are a couple despite being photographed kissing numerous times and friends say the pair really want to keep how serious their relationship is quiet.

The source told The Sun newspaper: ''They're basically living together. Like any new couple in love, they're pretty much joined at the hip. They've been sneaking around for months but there's only so long you can keep it quiet.''

Mila recently admitted she finds dating awkward but says it is easier to meet guys who are in the same business.

She explained: ''It does sometimes change the dynamic, in the sense that you're more well known and people presuppose more about you because they've seen your work and maybe read things about you.

''But usually you meet people in the same business, so you're not feeling awkward if you or the guy you met has just had a big film out, or whatever.''

Mila and Ashton have known each other for over 15 years, having found fame together on 'That 70S Show'.
