“All the kids were there, it was a gorgeous day full of sunshine and perfect for a pool party!!” she wrote in the newsletter.
“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 “Let’s Get Loud” hitmaker — who turned 54 on July 24 — also slipped into her birthday bikini, which happened to be a tiny Valentino two-piece ($980) with a green and white design.
In another video from the newsletter, she showed off her toned figure while posing poolside in her swimsuit and a black fedora.
Lopez finished off her sizzling look with gold bracelets and earrings paired with a chunky necklace.

The couple was seen enjoying lunch with the “Air” actor’s son, Samuel, 11, and Lopez’s twins, Emme and Max, 15, in Beverly Hills, Calif., on their wedding anniversary.
Affleck’s two daughters, Violet, 17, and Seraphina, 14 — whom he shares with ex-wife Jennifer Garner — weren’t present for the outing.
