Everybody might know his name, but to Jason Sudeikis, Cheers star George Wendt goes by Uncle George. The surprising celebrity relatives were spotted leaving a restaurant in Beverly Hills together on Feb. 21.

The casual pair both wore shorts and tennis shoes while on the fun family outing. Sudeikis, 38, has mentioned his relation to the '80s legend, 65, before. In a 2011 interview with Playboy, the Horrible Bosses 2 star opened up about his relationship with his uncle.

"He’s always been very encouraging, but there was no Tuesdays With Morrie kind of relationship between him and I," Sudeikis said at the time. "He didn’t take me to the park to explain comic timing. There was nothing like that. He was just a good example that being an actor was a viable option. Here’s a guy from the Midwest, in my family, who took the road less traveled and it worked out for him. The advice he gave me, and I say this jokingly, is 'Get on one of the best sitcoms of all time and then ride it out.'”

Sudeikis is a few short months away from being a first-time dad with fiancee Olivia Wilde. The pair are expecting a baby boy in May 2014.

"Sure I've looked like this after Mexican food but this time it's a BABY. #almostcooked #nineweekstogo #holyfu&$," Wilde, 29, recently captioned a Facebook photo of her pregnant belly.

One thing's for sure — if the tiny tot needs any advice from his great uncle, there's a good chance he'll be able to find him on a certain bar stool.
