Chip of the old block, they say. On the new episode of American Idol on March 10, celebrity judges Carrie Underwood, Luke Evans, and Lionel Richie were impressed by a 21-year-old contestant Baylee Littrell. The judges were already impressed by his singing when Baylee sprang a surprise and revealed that he was the son of Brian Littrell, best known as a member of the iconic boy band Backstreet Boys.

Baylee took the stage with an original song and impressed the three judges. Carrie was seen asking Baylee why he looks familiar, to which the young singer revealed that he was Brian's son.

While the judges clarified that only Baylee’s solo performance was being considered for the competition, they were still thoroughly impressed. Lionel Richie expressed his excitement, saying he was “very happy” for Baylee, while Carrie Underwood confidently predicted that he could go "very far" in the competition.
