The singer wore a sheer LBD which was cut out at the side showing off her incredible abs and revealed she wasn’t wearing a bra or knickers with the daring sheer detailing.
Body confident as always JLo didn’t care that she was freeing her nipples for all to see as she arrived hand in hand with boyfriend Alex Rodriguez.
The singer teamed the sexy outfit with sky-high strappy heels and large hoop earrings, and when she arrived at the bash had her hair long and cascading down her back, but obviously feeling the heat after a night of partying she left with it in a ponytail.
Jen – whose birthday it is today, had a joint celebration with Alex who turns 42 tomorrow.
He looked delighted to be partying alongside the sultry singer and looked dashing in a cobalt blue suit which he wore with a white shirt and unbuttoned collar.
Never doing things by halves, Jennifer celebrated with a huge white, gold and silver frosted tiered cake which took two men to carry into the party.
Speaking about the Miami party, an insider told E! News: “J.Lo was getting down on the dance floor with A-Rod and they both looked happily in love.
“The couple both drank and danced the night away, but were never out of control.
“It was the perfect night.”
The pair made their first official appearance as a couple at The Met Ball in May and since then have been gushing about one another.
Jen told Extra: “I feel really lucky right now.
“He’s a loving father. He’s a generous human being with his family, with his friends, with me.
“He’s caring and sweet and capable and responsible and just all the beautiful things you would want a man to be.”
