Careful when you're hating on celebs in public: they might be standing right behind you. That's what happened recently to passersby on Hollywood Boulevard who began bashing rapper 50 Cent only to find him glaring over their shoulders.

The sting was set up by Jimmy Kimmel, whose video crew went out to bait people into dissing 50 while the G-Unit rapper crept up behind them. But despite the thug image that he's used to sell songs like 'In Da Club' and 'Wanksta', 50 Cent was all smiles and hugs after surprising his haters.
