Stopping by to say hi, Ashton Kutcher visited Mila Kunis on the set of Jupiter Ascending in Joliet, IL on Wednesday (July 31).
The Hollywood pair squeezed in a quick private moment in Milas trailer before she got back to work.
According to reports, Ashton continues to stay by the 29-year-old actress side during the films shoots, travelling everywhere from London to the Chicago-suburb.
Last week, Mila shot a physically demanding scene with co-star Channing Tatum in the Chicago streets where the two were suspended from the back of a pick-up-truck.
Jupiter Ascending is set to hit theaters July 2014.
