Answer:
Yes,Justin has dated a young girl,Jocelyn Cyrus.Though,the two dated before his fame.
Jocelyn Nicole Cyrus,15 years-old,of Ontario Canada,was a dear friend of pop artist,Justin Bieber.Shortly after Justins fame increased,Jocelyn was killed in a tragic ATV accident on October 30,2009.When Justin was informed of her death he was astonished.'I did'NT even know what to say,my heart dropped,she had been my best friend my whole life and for her to just be gone,it didn't make any sense to me.I wanted to break down and cry.I-i felt horrible that i wasn't there to protect her.'He exclaimed.'Its kinda funny 'cause she and her mom had planned on coming to Atlanta the following week and we were text messaging just minutes before'He paused,"I'm gonna miss her so much,and Jocelyn,if you can hear me right now up there,I'm sorry.I love you babygirl".Our deepest condolences go out to Jocelyns family and friends.Your in our thoughts and prayers. -TMZ
