She’s a professional dancer, but everyone needs a night off.

Jennifer Lopez showed she’s an expert at finger dancing last night as she let loose from the safety of her sofa at a Las Vegas nightclub.

As the singer and dancer kept it low key, her toyboy boyfriend Caspar Smart leapt to his feet on the couch beside her, waving his hands around.

Perhaps Lopez was feeling a bit tired after her long day – which saw her host a pool party before taking to the stage to perform.

If she was it didn’t show in the mother-of-two’s appearance.

Jennifer had dressed to impress for her night out, displaying her curves  to maximum effect in a form fitting tight blue dress.

The former American Idol judge had earlier celebrated her Enrique and J-LO World Tour with a special appearance and pre-party at Wet Republic Ultra Pool at The MGM Grand Hotel and Casino in Sin City.

She wore a matching all-white crochet ensemble which consisted of high-waisted shorts and a cropped top which allowed her belly button to be visible.

From behind, the item even showed off her sculpted back, although much of it was covered up by her highlighted locks which were pulled back into a half-up-half-down style.
