Jennifer Lopez celebrated her World Tour Post Party at Pure Nightclub at Caesar's Palace in Las Vegas over the weekend.

The joint tour with Enrique Iglesias has been playing to sold out crowds across North America. It will end in Florida next month before Lopez goes solo in Europe and Asia.

The singer/actress wore a strapless electric blue dress with a striped pattern on the bodice that repeated down the back of her dress. She wore her hair in a half ponytail at the top of her head.

Earlier in the day Jennifer appeared at Wet Republic where she lounged poolside wearing a two-piece midriff bearing white ensemble by Bec & Bridge.
