Please help me figure out this super-catchy song I heard today!?

I was in the store "Finish Line" today when I heard the funkiest song, and I can't find it anywhere! The lyrics basically said over and over again, "I don't want to be alone" or "I don't want to be alone anymore" and "no no no no no". It was a hip hop beat, and the hook reminded me a little of "Jenny from the block", it was super super catchy. I googled the hell out of those lyrics, but all I am coming up with is some really old Billy Joel song. Please help me! I can't believe I can't find this stupid song. If y'all can't come up with it, I am gonna have to call the store tomorrow.... Help me out!
