David Schwimmer has revealed the awkward encounter he had with Sir Rod Stewart when he was 18. The Friends alum, 58, appeared on The Late Show With Stephen Colbert on Tuesday and admitted that he served the singer divorce papers during his short-lived career as a process server.

While Sir Rod celebrated his 80th birthday in style, the sitcom legend awkwardly revealed how he once served him divorce papers. Before his big break in 1994, David worked ‘so many jobs’ to pay his way through university, he told Stephen Colbert on The Late Show.
