Watch Justin Bieber Sing To His Mom On Mother’s Day

Justin Bieber had a Believe tour stop in Johannesburg, South Africa on Sunday (May 12), which, as you surely know, was Mother’s Day. So the star brought out his mom, Pattie Mallette, and serenaded her with a sweet rendition of “One Less Lonely Girl.” We don’t blame Biebs for wanting his mom close by on tour after that hairy situation in Dubai.

Watch the mother-son moment up top (Mama Biebs comes out at the 2:40 mark), and head below to see Bieber’s tweet proving he’s still a mama’s boy.
