Fall may technically start on Tuesday, but Jennifer Lopez isn’t quite ready to bid summer goodbye.

On Sunday, the 51-year-old pop phenom posed on Instagram in a tropical palm-print string bikini from Zimmermann ($185) that made the most of her awesome abs, along with a trio of gold Mini Mini Jewels dog tag pendants ($650 each) that spelled out “J-L-O” in diamonds.

“Vacation vibes 🏝🌊 #SummerNights #SummerSunset,” Lopez captioned her photo, in which she appears dripping wet while emerging from the ocean. She credited photographer Ana Carballosa for the sexy snap.

Christina Aguilera, Lisa Rinna and Francia Raisa all peppered the comments with fire emojis, while Drea de Matteo wrote, “Ay dios mío.”

Last week, the “I’m Real” hitmaker similarly set pulses racing with a sunset beach photo of herself “feeling golden” in a hot pink Emilio Pucci bikini ($400).
