Jennifer Lopez has been working out harder than usual ever since she started romancing former pro athlete Alex Rodriguez of the New York Yankees.

And the benefits are obvious, as she made clear in a new Instagram post shared on Thursday to her 98M followers.

The Amor Amor Amor singer looked slender and toned in a low-cut maroon swimsuit as she posed by a shore with a pair of burgundy-tinted aviator sunglasses and large diamond stud earrings.

It is not known where the star was photographed.

But it’s certain that she is already in Spain as she has a concert in Malaga on Thursday evening.

The Jenny From The Block singer captioned the shot, ‘3 more shows to go… soaking in every moment…

#itsmypartytour #asummeriwillneverforget See you tonight Malaga!!!’

Her fiance Alex shared another shot of her in the same suit to Snapchat on Wednesday.

Lopez was last seen after performing in Turkey.

Before that she was in Moscow where she put on a dazzling concert then hit the airport with her kids.

The singer, 50, had no time to change and was seen covering up one of her stage outfits in a bejewelled dressing gown as she picked up her twins Max and Emme, 11,  from their hotel in Russia.

The Ain’t It Funny singer looked radiant after another triumphant turn on the stage, revealing a glimpse of her hourglass curves in the skintight one-piece.

Proving that accessories truly can make an outfit, the mother-of-two toted a bedazzled drinking water bottle which bore her initials.

Meanwhile, the twins looked ready to catch up on sleep on the journey as they headed out clutching pillows whilst clad in matching red tracksuits.

The duo are no doubt enjoying spending the summer travelling the world with their mother, who began her It’s My Party tour in June, and will conclude in August.

The North American leg of the tour kicked off in June on June in Inglewood, California and ended her stateside stint in Miami, Florida, the following month after 32 shows.

Although the tour was originally designed to be in North American, the songstress later added dates across Europe, including a controversial performance in Israel.
