Actor Ashton Kutcher has reportedly asked girlfriend Mila Kunis to move into his Hollywood Hills mansion.
According to a source, the Kutcher's male roommate has already left in anticipation.
"They really are perfect for one another. They always have a lot of fun together," the source told usmagazine.com.
Friends of the couple said the 35-year-old is a huge fan of Kunis's desire to live a low-key, normal life.
"They like to chill out," added the source.
The 29-year-old, who has known Kutcher since she was 14 as they appeared on "That 70s Show" together, is said to be a huge hit among Kutcher's friends because she is so low maintenance.
"Mila is such a nice girl and extremely down-to-earth. Everyone on Ashton's team is happy for them," said the source.
