Demi Lovato is staying cool for the summer.
The pop star celebrated their 29th birthday in style, sporting a sheer white swimsuit by Frankies Bikinis in a series of sexy Instagram snaps on Sunday.
“Alexa play Birthday Suit by @duckwrth,” Lovato, whose birthday was on Friday, captioned the steamy slideshow from their vacation in the Maldives.
The star posed for both photos and videos, facing toward the ocean before hitting the waves.
Lovato’s famous friends flooded their comments with compliments, as Duckwrth wrote, “It ain’t Prada, naw it’s way mo cute,” while Chelsea Handler simply commented, “Nice tush.”
“Holy wow so heavenly beautiful,” Drew Barrymore added.
While Lovato’s racerback style is currently sold out, Frankies Bikinis has several other white-hot one-pieces available for purchase.
In addition to soaking up the sun, Lovato kicked off their birthday weekend by releasing the music video for their song “Melon Cake.” They rock a series of bold styles in the clip, including a cowboy hat ($219) and lace bodysuit ($130) teamed with a Dolce & Gabbana jacket ($5,985).
Lovato’s tropical getaway isn’t the first time they’ve heated things up this summer; they posted a bathtub selfie in July, before posing in a bra while opening up about filming their first sex scene.
The most recent post comes days after the star — who came out as non-binary in May and uses they/them pronouns — discussed their gender fluidity, revealing that they might one day identify as trans.
