Jersey Shore star Mike “The Situation” Sorrentino is suing a Las Vegas entertainment company for $60,000 he claims he’s owed for promotional appearances.

The reality-show celebrity, who also has been on Dancing With the Stars and The Tonight Show , claims in a lawsuit filed in Miami-Dade Circuit Court that Diversified Entertainment Group Inc. signed him up for a Couture Pop celebrity lollipop deal and a three-appearance package but arranged and paid for only one.
