Ashton Kutcher and Mila Kunis are reportedly living together in Chicago.
The couple has taken up residence in the Illinois state while she films Jupiter Ascending.
Apparently they are enjoying life in a luxury residence while she is hard at work.
"They're living in an apartment building called The Streeter," source told the US edition of Star magazine.
The lovers are seemingly taking plenty of time out to relax and enjoy each other's company.
They regularly attend the Massage Envy Spa when they want to wind down together.
"They came in on July 13 for a couples massage, and signed up for a standard three-month membership," an insider told the publication. "Ashton was very attentive to Mila. They were constantly hugging and calling each other 'babe'."
According to the onlooker, Ashton was constantly looking out for his partner to make sure she wasn't taken advantage of.
He allegedly rushed to the rescue when Mila was questioned about her upcoming work by staff.
"At one point, a male staffer was talking to Mila about her movie and Ashton got very protective," the source revealed. "He put his arm around her and said to the guy, 'You obviously did your homework.'"
Recently, Ashton arranged to go on a short fishing trip with his girlfriend where they caught their own dinner.
Ashton was previously married to actress Demi Moore.
