'Glee' star Chord Overstreet, who was introduced as Sam in Season 2 of the hit show, made his first appearance on 'Ellen' yesterday, and gave her (and the world) a little peek of his goods in a special pair of Ellen DeGeneres underwear.

The platinum-blond singer, who has become an instant 'Glee' heartthrob following his Justin Bieber tribute in the 'Comeback' episode, sported yellow boxer-briefs on yesterday afternoon's 'Ellen' -- and he wasn't afraid to show them. Overstreet pulled down his pants and exposed the waistband of the undies, which read 'Ellen' all the way around, and turned around to reveal his backside to the camera -- showcasing that the underpants said 'Ellen's Got My Tight-End Covered' on the butt.

When he wasn't mooning the camera, Overstreet dished to Ellen about where the name 'Chord' originated, his mutual admiration for Elton John, and how it feels to be shirtless on 'Glee' time and time again. Oh, and did we mention he's single?
