She recently announced plans for her first-ever global tour – and Jennifer Lopez made sure to end the South American leg of her trek with a bang last night.

The singer took the stage in Recife, Brazil, flaunting her famous six-pack abs in a dazzling gold and silver sequinned track suit.

Braving the rain in the outdoor arena, the hard-working mother-of-two ripped open her hoodie, revealing the chiselled results of her gruelling dance routines on the 48-show Dance Again tour.

Wearing a sequinned New York baseball
cap, her brunette locks soaked from rain and sweat, the 42-year-old star grabbed
her gold microphone and continued with her set despite the downpour.

Her dancers – a group of equally-chiselled men – didn't waver either, and joined the singer on stage as the crowd roared.
