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.
