Ellen DeGeneres was proud to show off Greyson Chance, the first artist signed to her record label eleveneleven. The perfectly coiffed duo hung out backstage at the Teen Choice Awards.

Both were grinning from ear to ear ... celebrating their Teen Choice nominations. Ellen was nominated for "Choice Comedian" and "Choice Twit" ... and Greyson, 12, scored a nom for "Choice Web Star." Props to Ms. DeGeneres ... she won both her awards!

You can see all the teen action tonight when the Teen Choice Awards airs on FOX.
