The Jenny From The block singer revealed her toned physique and curves in a tie-up black bikini that feautured white and green swirls.

She accessorised with chunky gold bangles and earrings, and a white chain choker.

The mum of twin, who credits her trim figure to five workouts a week, added a touch of glamour for her birthday pool party with smokey eye make-up and pink lip gloss.

Reacting to her snaps on Instagram, one fan said: “Are you sure you are 54? You are so beautiful and look maybe 34 maybe!!!! I hope you had a fabulous birthday!!! Looks like you did!!!”

Another raved: “Aging like fine wine.”

“You look like you are 34, not 54. You’re a very classy lady,” a third penned.

The US star was 54 last week, and she threw a pool party at home with her Hollywood actor husband Ben Affleck, 50.

She has been sharing updates on her life on her website, On The JLo, and told fans about it: “Ben hosted it at our new house with our closest family and friends.

“It was a gorgeous day full of sunshine and perfect for a pool party!!

“I felt so appreciated by my loved ones, and I’m extremely grateful.”

She celebrated her 54th birthday by dancing on a table.

The American singer threw her arms out as she partied in a long, backless silver dress with her friends and family.

The star, whose big day was on Monday, shared the photos on Instagram and told her 249million followers: “Birthday mood  . . . all month.”

Jennifer and Ben Affleck married in July 2022, much to the delight of fans, after previously getting engaged in 2002, before calling it all off.
