Justin Bieber had something special up his sleeve for his mom, Pattie Mallette, on Mother's Day: a sweet serenade.

While the 19-year-old pop star performed to a sold-out crowd in Johannesburg, South Africa, on Sunday night, he surprised both the audience and his mom by bringing her up on stage and dedicating his popular song "One Less Lonely Girl" to her. (Cue the awwwws.)

Just after the show, the singer took to Twitter to further express his love, writing, "Happy Mother's Day @PattieMellatte. Today U R my #OLLG. Love u." Pattie was, of course, equally touched by her son's thoughtful gestures and tweeted, "So yep … @JustinBieber surprised me for Mother's Day tonight & brought me out for OLLG! #VerySweet!" Very sweet, indeed! Good to see the Biebs hasn't forgotten where he came from.
