Jennifer Lopez celebrates 56th birthday in curve-hugging backless gown

How low can J Lo’s dress go?

Jennifer Lopez celebrated her 56th birthday on Wednesday night in Turkey, partying in style backstage at one of her shows.

The singer changed out of her skimpy on-stage outfits and into a slinky metallic gown that closely hugged her famous curves. The design included a halter neckline and a super low-cut back, showing off some skin.

The multi-hyphenate piled on the bling with tons of chunky bracelets and rings and wore her signature hair down to her butt.

She was seen dancing to her new single — appropriately titled “Birthday” — in Instagram videos posted to her Story. Plus, the superstar was presented with a massive three-layer cake and held a cocktail in her hand as backup dancers and waitresses celebrated around her.

Earlier in the night, Lopez debuted her new song live on stage at the Regnum The Crown resort — and the lyrics did not disappoint.
