We weren't the only ones paying homage to Justin Bieber's mom Pattie Mallette yesterday! In honor of Mother's Day, Justin surprised her at his concert last night in Johannesburg, South Africa.
The pop star had Pattie join him on stage, where he gave her flowers and sang "One Less Lonely Girl." Talk about cute!
Watch a video of the performance below, and let us know in the comments if you think Justin is the best son ever!
