Mila Kunis and Ashton Kutcher are reportedly thinking about shacking up together.

The Hollywood stars are rumoured to have been dating for several months now.

Although Ashton is still legally married to his estranged wife Demi Moore, the actor thought it appropriate to ask Mila to move in with him.

Apparently the pair are inseparable at the moment.

"Ashton and Mila are completely in loveand since they spend so much time together, he decided to take a leap of faith and ask her to move in," a source told Star magazine.

Ashton is eager to get Mila involved in giving his man den a spruce up.

The star is said to have requested that Mila add her flair to the Hollywood Hills home.

"They've even made house decorating a joint project," the source explained.

"Ashton insisted Mila have input so she didn't feel like she was living in a bachelor pad."
