Jennifer Lopez, 54, flaunts her age-defying physique in a tiny black Valentino bikini in sexy clip from her birthday party

Jennifer Lopez made jaws drop when she shared a video of herself modeling a bikini to Instagram earlier this week.

The superstar — who recently celebrated her 54th birthday — flaunted her enviably toned physique in a tiny black Valentino two-piece that retails for $980.

To glam up her look, Jennifer was decked out with flashy jewelry, a stylish black fedora hat and sky-high heels.

She rocked a full-face of makeup that enhanced her natural beauty and her honey-toned hair flowed down her chest.

The On The Floor singer stood in front of a stunning infinity pool with an incredible view of the lush landscape and clear blue sky in Beverly Hills.

For one shot, she posed with her hands behind her head and one foot forward to show off her hourglass shape.

She removed the hat for several photos and used it to conceal her famous backside as she turned away from the camera. 

The wife of Ben Affleck shared the sexy clip with her 250million followers on Monday.

It was taken during her birthday bash last week at her and Ben's new $60million Beverly Hills mansion. 

She shared more moments from the party — which took place last Monday on July 24 — to her On The JLo newsletter this week.

One clip saw the Hustlers star dancing in a backless halter neck silver gown that clung to her toned figure as she performed for her guests atop a table to Lizzo's hit song About Damn Time.

While Lopez grooved from above her guests were seated around a table and cheered her on.

'Birthday mood… all month!! It’s always a good day when Lola comes to play,' she wrote of her alter ego.

Despite wearing pointed toe heels with bows Lopez expertly navigated her way on the wooden table while showing off a range of dance moves.

The singer wore her honey brown tresses pinned halfway back for the party.

She accessorized with drop earrings and a number of silver bangles.

As for glam she looked picture-perfect with bronze eyeshadow and nude gloss.

Lopez shared details of the party in a letter to her subscribers, revealing their blended family all got together to celebrate.

'All the kids were there, it was a gorgeous day full of sunshine and perfect for a pool party!!' she wrote.

'I felt so appreciated and acknowledged by my loved ones, and I’m extremely grateful to be where I am today at this point in my life’s journey with so many beautiful, caring people to share it all with.'

'Wishing you all the same love and happiness on your birthday and always!!!'

The pair are raising their combined five children - Violet, 17, Seraphina, 14, and Samuel Affleck, 11, from Affleck's marriage to Jennifer Garner, plus Lopez's fraternal twins Emme and Max Muñiz, 15, from her marriage to Marc Anthony.

Jennifer also recently celebrated her first wedding anniversary with her Oscar-winning husband.

The two enjoyed back-to-back weddings in 2022, including an intimate ceremony in Las Vegas.

In June the Bronx native and her husband of one year snapped up a Beverly Hills mansion for $60million.

They have been remodeling the large property for a month and are in the design stages.

Jen and Ben found their dream home after nearly a year of searching.

The married couple paid $60.85 million in cash for the magnificent 46,000 square-foot mansion, according to TMZ.

The home — referred to as the 'Wallingford estate' — sits on a 5-acre promontory and boasts 12 bedrooms and 24 bathrooms.
