A suburban teenager has gone from Internet hit to halftime entertainer.

Keenan Cahill performed Sunday at Public House in Chicago during halftime of the Bears game.

The 15-year-old is a hit on YouTube for the videos he posts of himself lip syncing to popular songs.

He even got the attention of rapper 50 Cent, who joined Cahill on one of his videos.

Cahill said all this has been "a dream come true."
