JUSTIN BIEBER

There's no questioning the Biebs's love for his mother. During a 2011 Berlin concert, he surprised mom Pattie with a birthday cake, but as she blew out the candles, strands of her hair caught on fire. Luckily, Justin was there put out the flames. Shortly after the hair-raising incident, the pop phenom and mom continued to their next tour stop in China without incident.
