Ashton Kutcher's shiny crystal-studded gift for Mila Kunis

Taking their rumoured romance to another level, actor Ashton Kutcher has bought Mila Kunis a USD 5,000 crystal-studded phone case engraved with both their initials.

The Two and a Half Men actor designed the bejewelled case himself, with pink crystals and a heart encircling both their initials in real diamonds, leaving the actress thrilled, reported National Enquirer magazine.

"He spent five thousand bucks on Mila's case. Needless to say, she loved it!," said a source.

Kunis and Kutcher are apparently living together and the former That '70s Show co-stars are inseparable from each other.

"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. They're staying with each other most nights. Mila's practically moved in to Ashton's Hollywood home," said the source.

Ashton's marriage to Demi Moore broke down last November, following reports of his cheating and the Ghost actress is said to be devastated he has now found love with Mila.
