After 22 years interviewing the best in Hollywood, Jay Leno
was bound to make a few A-list pals.
His final Tonight Show broadcast
was full of special celebrity guests
, and stars who couldn't join in the festivities sent Leno love through social media.
Sure, rival Conan O'Brien
allowed himself one solid wisecrack during his own show: "The Olympics start airing tonight on NBC. It's very cool. That's right: NBC has the Olympics. It's a big deal. NBC will finally get to show somebody who is okay with passing the torch."
But overall, online reactions to Leno's last show were heartfelt and nostalgic.
From singers like Justin Timberlake
and Josh Groban to comedians Whoopi Goldberg
and even competitor (and onetime critic) Jimmy Kimmel
, it seemed everyone had plenty of praise for the nice guy of late night
PEOPLE rounded up Tweets and Instagrams from some of Leno's most famous friends. See what they had to say about the departing host:
