JLo looked like a screen siren in a 50-style white halter dress with backless detail, which she teamed with a tousled updo and gold heels.

The mother-of-two flipped up the skirts of her dress and did some fancy footwork as she threw shapes in one of the lounges of the megayacht.

She finished off the routine by sultrily sashaying down to the ground with her hand in her hair.

Her friend shared the video on his Instagram Stories with the caption: “Share that beat of love.”

SUMMER OF LOVE

Earlier in the day, JLo was seen holding hands with Ben as they strolled around the streets of Capri, Italy.

The singer and actor celebrated her 52nd birthday in St Tropez on board the Valerie yacht last week.

And the superstar couple have now left France behind for Italy, having stopped off at a port in Monaco.

They seemed to be in great spirits, chatting and laughing away as they took in the sights with a group of friends.

Last week, they recreated JLo’s iconic 2002 Jenny from the Block video on board their massive yacht.

The duo, who rekindled their romance last April, looked smitten as Ben rubbed a bikini-clad JLo’s butt while they sunbathed on the deck.

AROD’S YACHT TRIP

Amidst their loved-up getaway, JLo’s ex-fiancee ARod is enjoying his own yacht trip to celebrate his 46th birthday.

He was seen partying with a slew of bikini-clad women in France on the same day that JLo confirmed her romance with Ben on social media.

She went Instagram official with the Gone Girl actor by posting a photo of them kissing on the social media site.

She drove her fans wild as she shared the cute snap of the rekindled lovers kissing in a post marking her 52nd birthday.

An insider recently told PEOPLE that the couple “are madly in love” and “the loves of each other’s lives”.

In 2004, JLo and Ben broke off their relationship just days before their planned wedding and within a year, were married to other people.

But Ben is keen not to let history repeat itself, and is said to be planning to get down on one knee and ask JLo to marry him “before the end of the year”.

JLo shares 13-year-old twins Maximilian and Emme with ex-husband Marc Anthony, while Ben is the father to daughters Violet, 15, and Seraphina, 12, and son Samuel, nine, with ex-wife Jennifer Garner.
