Justin Bieber torches mum's hair!
Justin Bieber surprised his mother with a birthday cake on stage after a concert in Germany - and accidentally set her hair alight.
The 17-year-old teen heartthrob invited his mother Pattie Mallette on stage at the end of his gig at the O2 in Berlin at the weekend to celebrate her turning 35, and presented her with a cake as the audience sang Happy Birthday.
But as Pattie leant over to blow out the candles, a few strands of her hair caught fire and Justin had to quickly pat out the flames before hugging and kissing her.
The Baby singer later tweeted: "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."
Pattie tweeted: "Thank u @justinbieber for the cake (& embarrassing me on stage lol.)"
