Jennifer Lopez, 54, takes RACY selfies of her famous booty on solo vacation

Jennifer Lopez showed Ben Affleck exactly what he is missing as she sizzled in a plunging white swimsuit on a luxurious getaway to Italy with friends amid their rumored marital troubles.

While enjoying her trip to Positano as her spouse, 51, remained home in Los Angeles, the 54-year-old superstar appeared to be having the time of her life as she cruised around the the west side of the Amalfi Coast on a speed boat.

An eyewitness told DailyMail.com that the Let’s Get Loud hitmaker appeared in ‘great spirits’ as she let loose with friends and could be seen dancing and having fun on the boat.

In addition to taking in the stunning scenery around her, the mother-of-two, who shares her 16-year-old twins Max and Emme with ex-husband Marc Anthony, posed for selfies from various angles and even snapped a few of her famous derrière.

It’s unknown who she was sending her flirty snaps to, but over the years, Affleck has been fond of boating with Lopez, and, memorably, recreated an iconic scene from her 2002 Jenny From the Block music video on a $130M dollar mega yacht as they vacationed together in Saint Tropez for her 52nd birthday after they first rekindled.

She styled her low-cut low-piece with a pair of gold hoop earrings, two matching bangle bracelets, a pair of oversized sunglasses and her light brown hair in a sleek bun.

The Grammy nominee’s rare green diamond engagement ring remained in place on her wedding finger, despite reports she and Affleck are ‘living separate lives’ and selling their $61 million marital home.

The Atlas actress exuded confidence as she the stern of the boat in her sexy bathing suit and a pair of open-toed high heels as pals rushed to capture the moment of her relaxing at sea.

Before stripping down to her swimsuit, she wore a brown romper, which she later tucked into a Christian Dior tote bag.

The performer, who recently said that she is ‘thinner’ than ever after training for her film, Kiss Of The Spider Woman, has previously credited her fit figure to kickboxing, circuit training, core work and burpees.

‘I’m the thinnest I’ve ever been. I’m in fighting shape right now,’ she said on Live With Kelly and Mark last month.

Last year, she opened up about how moving her body helps her keep a positive mental attitude.

‘It’s no secret that fitness is a very important part of my life,’ the star told Us Weekly.

She continued: ‘I think there’s a positive correlation between exercise and mental health.’

Lopez went on to say that she believes that once ‘you find a good balance through determination and focus’ you’re able to to ‘be the best version of’ yourself.

I’m not afraid to challenge myself, so I’m open to pushing myself, which is what I’m doing right now as I rehearse for my new album, [This Is Me… Now].’

When her career first took off, she paid less attention to stress.

‘There was a time in my life where I used to sleep 3 to 5 hours a night. I’d be on set all day and in the studio all night and doing junkets and filming videos on the weekends. I was in my late 20s and I thought I was invincible,’ she wrote in On the JLo in July 2022.

‘Until one day, I was sitting in a trailer, and all the work and the stress it brought with it, coupled with not enough sleep to recuperate mentally, caught up with me.’

Then she felt ‘frozen.’

‘I thought I was losing my mind. … Now I know it was a classic panic attack brought on by exhaustion, but I had never even heard the term at the time.’

After consulting a doctor, the New York native said she ‘realized how serious the consequences could be of ignoring what my body and mind needed to be healthy — and that’s where my journey to wellness began.’

Lopez’s latest sighting comes after Affleck spoke about her in an new interview, filmed months ago, as he shed light on what it was like being wed to someone so famous.

We went somewhere with [Jennifer]—I can’t remember because she’s so famous, and she creates this—people love her, and she really represents something important to people,’ Affleck began

‘[To me,] people are like, “Hey, I like your movie,” and then they’re like “AAAHHHH! J-LO!” he yelled. ‘It’s amazing, you know what I mean?’

Then he got more specific.

‘I think it was when we rolled through Times Square,’ he continued.

‘We get out of the car, we were going to a play, and I was like, “F*** it, babe, we’re going to be late, we gotta walk a block and a half.” [Lopez] was like, “Alright,” she didn’t say s**

They were with all their children – he has Violet, Seraphina and Samuel with Jennifer Garner and Lopez has Max and Emme with Marc Anthony.

‘We get out with her, all the kids, through Times Square, and the s*** was like f****n’ bananas,’ Affleck noted.

‘I was like, “Oh my God.” There was a lady, she was smoking weed, in a full purple skintight suit—she’s a heavy lady—and she starts running backwards filming, going “J-LO!!”

He added, ‘Like a herald, that then gets everyone else, and then all the tourists come in.’

Then we’ve got our five kids, it’s me and Jen and what feels like hundreds of people, and they’re all screaming.’

When he began telling the story to Hart, he said his daughter has this thing where she is ‘always throwing out titles to her autobiography.’

His daughter, he doesn’t name which one, then turned to her dad in Time Square after the frenzy began and said a titled for her autobiography could be: J-Lo Was My Stepmother.
