VIDEO: Darren Criss sings 'All of Me' on Glee

Darren Criss sang 'All of Me' on the season finale of Glee.

This was so good. Blaine played the piano and when Kurt arrived, he sang to him! How sweet.

Love this song from John Legend.

Glee will return midseason in 2015 for its final season set in L.A.
