Well, this should surely teach people not to mess with Selena Gomez!
However, that's no reason to get physical, gurl!
Ch-ch-check out the pap pushing vid...AFTER THE JUMP!!!
According to a rep, "She was doing a signing to launch her new book. Hundreds of fans had been queuing since last night. A guy came up and punched her to the side of the head. She is absolutely gutted she did not get the signings finished."
Leona sustained bruising to the side of her head and was left "shaken" by the incident.
Lewis was quickly escorted out and spotted in tears (above).
Thankfully, the douchebag that punched her was arrested, though no information has yet been released as to why she was attacked. We can only image the guy must have some mental issues.
Why else would he hit her?!?
