Jennifer Lopez sparked concern amongst her fans yesterday after posting photos of what appeared to be riot scenes via her official Twitter account.

The 'On The Floor' hitmaker took to the social networking site last night, August 21, and wrote "#omg yesterday got a 'lil hectic".

She followed up the message with a photograph of an overturned car encased in flames with an angry mob of rioters stood in front of it.

Lopez then sent out another tweet that read, "it was out of control yesterday!!!!!", which was accompanied by another picture of similar content.

Following an influx of replies from her worried followers, she reassured them that the pictures were stills from the set of her new music video for 'Papi'.
