Could Mila Kunis get an engagement ring for the holidays? The "Jupiter Ascending" actress, 30, is spending her second holiday season with boyfriend Ashton Kutcher and family (this past weekend, Kunis and Kutcher, 35, were spotted in his native Iowa) -- and, now that Kutcher and ex Demi Moore have at least finalized their once-contentious divorce, the private but captivating couple are gearing up for the next step, multiple sources tell Us Weekly.
Dating for nearly two years, the former "That '70s Show" costars are "inseparable," another friend notes. When not working herself, Kunis is a frequent visitor to the set of Kutcher's super-smash sitcom "Two and a Half Men." "They hang in his trailer," a set insider says.
The Ukrainian-born beauty has helped mellow out the former party boy, who legally parted ways with Moore, 51, back in November, two years after their dramatic split. Instead of wild nights out, Kutcher and his beloved prefer nights in at their shared $10.8 million Hollywood Hills, Calif., home. "Ashton and Mila cook together," a Kutcher pal says. "He knows he ended up with the right girl."
