"That wasn't drunk swaying, that was professional dancing!"

Jessica is currently filming her new reality show Fashion Star alongside Nicole Richie.

But it is being reported that there is already drama on the set of the show which will help find the next big fashion designer.

"Nicole has made a few digs about Jessica throwing her weight around' while Jessica has joked that someone would have to be on a starvation diet to wear Nicole's designs," Hollywood Gossip is stating.
