Conan O'Brien celebrates final 'Tonight Show'

Conan O'Brien has reportedly celebrated his final Tonight Show episode with an Irish bash.

Following Friday night's taping of the last Tonight Show With Conan O'Brien, the former host was joined by Will Ferrell, Andy Richter and 200 of his co-workers at a goodbye after-party, PopEater reports.

O'Brien, who parted with the NBC network after being moved later in the new schedule, thanked the channel and his viewers on the farewell show.

A source revealed that the party included Ben & Jerry’s ice cream, sushi and Jameson Irish Whiskey, which went quickly as "guests drained magnums".

The comedian was spotted socialising with celebrity friends but spent most of the evening posing for photos with his entire staff, as they dressed up in 'Team Conan' t-shirts.
