Jennifer Lopez and Marc Anthony in Athens

It's been a busy week for superstar Latino singer Jennifer Lopez.

First the 39 year old completed the Nautica Malibu Triathlon in two hours, 23 minutes.

Then, after departing for a supposedly "relaxing" European break (Portofino and St Tropez - there's a surprise), she's jetted out to Athens for two days to perform at the Olympic Stadium for the first leg of her World Tour, promote her latest boutique AND take part in a photo shoot at the Acropolis in Athens.
