OK, "Mm-m-mm, my mommy's on The Voice," might be our new favorite song.

That's the impromptu tune Alicia Keys' 5-year-old son, Egypt, started belting out when he found out that the "Girl on Fire" singer would be joining season 11 of the reality-competition show.

Alicia will be on the show as a coach, her rep confirmed to ET earlier this month. The singer was previously a mentor for Team Pharrell on season seven in 2014. Miley Cyrus will also be a coach during the upcoming season as well.

In the meantime, Egypt is obviously still taking after his mom and dad, Swizz Beatz, in the music department!
