Ahead of her birthday on July 24, the "Jenny From the Block" singer shared an unfiltered glimpse into her recent European vacation, including the unconventional place she and her sister Lynda Lopez—who turned 55 on June 14—enjoyed a sweet treat together in honor of their milestones.

In a photo posted on Instagram July 19, J.Lo was pictured nude in a bathtub eating a dessert, while her younger sibling sat on the bathroom floor snacking on her own dish.

"A double birthday sister trip is always a good idea," she wrote in the caption. "I love you Lynnie!! Happy birthday!!"

But the celebrations didn't end there. As seen in other pictures included in the same post, Jennifer and Lynda also went sightseeing at La Galerie Dior in Paris, before being surprised with not one, but two birthday cakes durings a dinner with friends.

And the Wedding Planner alum was certainly dressed to the nines for the occasion. After all, she wore over 400 carats of diamonds from Chopard throughout her glitzy getaway.

At her birthday dinner alone, Jennifer donned statement necklace boasting over 190 carats of diamonds—as well as a pair of 19.22-carat diamond earrings, a 73.69-carat diamond bracelet and a 6-carat diamond ring—along with a Tamara Ralph gown.

She was also spotted out to another dinner at Paris hotspot Gigi's on July 10, sporting a nearly-naked dress designed by Zuhair Murad embellished with crystals that sparkled next a set of chandelier earrings adorned with 6.28 carats of diamonds and a whopping 68.03 carats of white pearls.

Lastly, Jennifer rounded out her party outfits with a white turtleneck number by Stephane Rolland, which she paired with a jewelry set studded with over 42 carats of rubies and 112 carats of diamonds. In addition to the necklace and the earrings, the 56-year-old donned a white gold ring decorated with 2.82 carats of marquise-cut diamonds.

"Just this feeling," Jennifer captioned images of her three birthday looks in a July 10 Instagram post. "Birthday celebrations in Paris!"
