When you say the words ‘curves’ and ‘booty’ you tend to think of two people – Kim Kardashian and Jennifer Lopez.

But the stars are far from being rivals as Kimmy gushed about the singer after seeing her wearing THAT racy dress to her 46th birthday bash in New York.

Posting two side-by-side pics of Jenny From The Block on Twitter and Instagram, the reality star wrote: “Damn!!!!! How hot does @jlo look!!!!! She will forever be my idol!!!!#BodyGoals.”

The superstar, who threw a lavish bash at 1 OAK nightclub to mark the special occasion, looked decades younger in the revealing frock and she managed to throw some serious shapes wearing it.

New photographs from inside the party show her getting cosy with on/off boyfriend Casper Smart before posing with pals and getting wild on the dancefloor and throwing her arms in the air.

She draped her arm over the dancer while leaning up in a pair of strappy heels and he looked like the cat who got the cream, smiling while trying to keep his hands off his missus.

She slipped into one of her most sexiest outfits ever to celebrate her big night on Friday in new York, after debuting a much shorter hairstyle. We approve.

The singer managed to distract fellow guests from the fact that she had turned another year older by wearing the outrageously racy dress.
