The 'Two And A Half Men' star and his actress fiancee - who are expecting their first child together - attended the nuptials of Tausha Kutcher, who is also pregnant, and Ken Kordisch, in the gardens of Woodridge Bed and Breakfast in Pearl River, Louisiana.
The venue's owner, Debbie Fotsch, told RadarOnline.com: ''It was a thrill. Quite a surprise! We knew that a couple was getting married and we knew the last name.
''I sort of in my mind teased around asking if her brother was Ashton. But I didn't. What are the odds! They walked up to the door and we opened it up to people we only see on TV.''
The wedding on April 16 was a low-key affair with the bride wearing a short white dress, while Ashton, 36, donned khakis and a white shirt and Mila, 30, covered up her growing baby bump in a long black skirt and jacket.
Debbie, who runs the bed and breakfast with her husband Tim, continued: ''They chose us because it was private and secluded area.
''They weren't followed. They seemed pleased that they weren't having to look over their shoulder.
''It was actually our wedding anniversary so that was the only wedding we were going to do that day.
''They were utterly wonderful people.''
Ashton's sister and her new husband also spent their first two nights as a married couple at the picturesque hotel.
