Bryanna Debinder, 20, from Pennsylvania in the USA, has lost 7 stone in order to impress her idol. The psychology student first became obsessed with the Canadian heart-throb in 2009, after seeing his 'One Time' video on MTV. After becoming jealous of the girls he pulled on stage, she embarked on a diet that has seen her drop from 19st to 12st. Bryanna, who has never had a boyfriend, says she is 'in love' with Justin, and just wants to let him know that he has changed her life forever. 'He's my ideal boyfriend,' said Bryanna.
