“Hey, I got news for you. You’re gonna be grandparents,” Murray says in the video. “We’re having a baby!” adds Robbie.
The couple was sitting next to Murray behind home plate during a Chicago Cubs baseball game on 9 October. “We talked casually during the game and he playfully switched glasses with Kirsten for a minute since his shades make the entire stadium turn blue,” Robbie wrote when he shared the video with the popular Love What Matters Facebook page.
“After the Cubs win I told Bill I needed him to make our pregnancy announcement. Kirsten struggled with fertility so we had decided not to make it public at first but this was too fun to pass up,” he explained. “Bill gladly recorded the message for us and we got a few cheers from the crowd still standing around us.”
The reaction from the grandparents-to-be was apparently very emotional. As Robbie noted in his caption, “Bill Murray, thank you for making my parents cry!”
