Live is celebrating its 50th anniversary this weekend with a slew of guests from the show's history, but one Oklahoman will be missing.

Social media loved SNL50, but it was disappointed that Bill Hader didn't make an appearance. This is why he wasn't at the show.

Leading up to the Sunday, February 16, event, NBC has announced the dozens of stars who will making appearances, including several SNL alum. Hader was on the show from 2005-2013 and portrayed the fan-favorite Stefon, so his absence from the list of attendees was noteworthy to fans, who expressed their frustration on social media.

Live alum Bill Hader, who created iconic characters like Stefon during his tenure on the comedy series, was absent from the SNL 50 anniversary special and his rep has revealed why.

Why didn't Bill Hader attend the 'Saturday Night Live' 50th Anniversary Special on Sunday, Feb. 16? His representative tells TODAY.com it was due to a "longstanding schedule conflict."
