justin bieber's heres what I found in him:
In the April 19, 2010 issue of People magazine Justin was quoted as saying, "I don't have a girlfriend right now. But I'm 16. I just like to hang out with girls and stuff."
Justin Bieber has previously dated Caitlin Beadles. He has not publicly spoken of a current girlfriend, or released any official statements about a new girlfriend. Until he does so, his personal details remain private, unless he chooses to release them to the public. He has admitted though, that he has no time for a relationship.
