The Biebs went all out for his momma, and surprised her with a cake and candles for her birthday, live during his show. That little surprise almost turned out for the worst....almost. Check it out:
Right after the show Justin hopped on his Twitter to let us know,
"Sick show in Berlin... brought @studiomama on stage 2 sing her happy bday but she lit her hair on fire with the candles. lol. i saved her."
His mom, aka Studio Mama, wrote on her own Twitter page as well,
"Thank you for all your b-day wishes!! All I want is your prayers. Thank u @justinbieber for the cake (& embarrassing me on stage lol.) Xo."
