I don't really have an opinion on his singing. I've never heard much of anything but "Baby, Baby" or whatever it's called. I did hear some things from a person I know that probably put me off on him a little, but then, he's very young and new to all the attention.
He attended a party a Shaq's house, here in Orlando, last year (prior to Shaq's move to Boston). He was in town for a charity thing with Shaq. My friend lives a couple of houses away from Shaq's house. Her kids were friends of Shaq's kids so they were invited to the party. The girls wanted to have their picture taken with Justin. The only way he would agree to it was if my friend let him drive their Nev (it's an electric car a little bigger than a golf cart) around the neighborhood. At the time, I don't think Justin had a driver's license and the Nev is a street legal vehicle. In the end, they let him drive the Nev and the girls got their picture, but they were pretty disappointed in the way he treated people at the party.
