Singer and 'Fashion Police' host Kelly Osbourne has criticised the Polish paparazzi after clashing with them earlier today when she arrived there.

Writing on her official Twitter page this morning (March 25), the star explained that she had been shoved and knocked around by photographers, which is just unacceptable:

"Dear #poland paps I love being here & am extremely honored that you even care about me but please don't push/hit me or my fans! Its not ok!"

It's been a stressful month for Osbourne after she suffered a seizure while on the set of her style show, but she recently revealed that she's recovering well and it was likely that it was a one-off episode.
