Ashton Kutcher and Mila Kunis were spotted on the set of Downton Abbey this week.
The pair who are currently expecting their first child together took a trip to the set of the ITV period drama during the making of the new series, kicking off this weekend.
Lady Mary Crawley actress Michelle Dockery said she was elated to discover the Hollywood A-listers would be visiting, noting that they're huge fans of the show.
Speaking to Radio Times Magazine she said: "It's true Mila and Ashton came to visit us on set. They're big fans and were lovely!"
The series has picked up a score of celebrity fans include J.J. Abrams - famous for directing Star Trek - and Maggie Gyllenhaal who wants to join the cast.
Anyone new joining though would have a "family" to penetrate.
Michelle explained: "We're all like a family on the show. Hugh Bonneville plays my father, which is weird because he's just my mate!"
Downton Abbey returns Sunday, September 21 at 9pm on ITV.
