Jennifer Lopez, 50, shows her engraved abs and tingling pins at Magic Johnson's birthday in St Tropez

They started dating in February 2017 and announced their engagement in March.

And Jennifer Lopez and Alex Rodriguez were happy when they arrived at Nikki Beach in St Tropez to celebrate the sixtieth birthday of basketball star Magic Johnson on Monday.

Jennifer was nothing short of sensational for the outdoor party while she was displaying her flawless physique in a white short-sleeved long-sleeved top.

Jennifer's dedication to fitness has paid off as the singer posted her engraved abs as she headed for the beach after a boat trip.

The actress also wore a flowing blue dress with a white dotted print and a bold vent on her leg.

Jennifer presented her toning pins and added height to her frame with a pair of thick heels, while wearing a large pair of sunglasses.

Putting her curls in an elegant bun, the singer completed her look with a cream-colored handbag.

Alex chose a white long-sleeved shirt, which he paired with matching jeans and aviator sunglasses.

Hollywood actor Samuel L Jackson, who arrived by boat with several guests, was another famous celebrity of the festivities.

The actor dressed casually for the evening of a purple t-shirt and matching shorts that he paired with multicolored sneakers.

Magic's son, CJ, was another party guest and wore an electric blue shirt that he tied around his waist with a coordinating wrap skirt.

Alex and Jennifer landed in St Tropez by plane with singer On The Floor making an elegant silhouette for her trip.

She descended from the plane with style, wearing a cream blazer and a matching top that she paired with white jeans.

Wearing big thick sunglasses and loops of ear curls, Jennifer also donned a pair of brown heels.

Alex opted for a casual look for the trip and wore a light blue hoodie and matching pants.

The release of Alex and Jennifer comes after the baseball star offered him a car at their home in Miami for his birthday during the summer.

In a video posted on YouTube, the 44-year-old athlete surprised Jennifer with a red Porsche 911 GTS 2019.

The video shows A-Rod plotting with his children and those of J.Lo about what to buy from the woman who has everything.

He said: "There is a lot of pressure because it's Jennifer's birthday, July 24, and we've been thinking about how to get Jennifer for her birthday."

"What do you get someone who already has everything?" You must be creative.

He continued, "We may have talked about a car. The irony is that we will buy her a car, but she has not driven for 25 years.

They finally opted for the brilliant red Porsche, whose starting price is $ 120,700.

After carefully planning the surprise with the kids, Alex blindfolded her birthday girl and took her to see her surprise.

In shock, she said, "Oh my god, am I going to have to drive? I have never driven a car like this … I have never driven a car, period.

But that sounds like a bike, because she immediately got behind the wheel for a cruise in their neighborhood.

The couple's vacation is a well-deserved break for Jennifer, who will then be seen on the big screen in Hustlers, a detective comedy about a group of strippers in New York.

The star embodies Ramona Vega, a single mother who advises the new girl Destiny (Constance Wu) and helps her set up a scam to support herself.

The singer had previously told Fandango that his pole dance moves were "really difficult" and that it took "talent".

She said, "In fact, it's really hard to do that [moves]. It takes skills. It's not as if anybody could just jump up there and do this … I've had a lot of bruises and other things.

Jennifer also added that she wanted to live in the gigantic platform that she wore in the trailer. [You feel] short and stocky!

"When you put them for the first time, you're like a baby deer. You walk, you are well, and suddenly, your legs give way. And suddenly, they are like ballet slippers and you can not dance without them.
