Rihanna turns 37 today … and, we’ve got the “Pon De Replay” of all her sexiest snaps to celebrate the momentous milestone.

The singer-songwriter’s not afraid to strip down to her skivvies for any reason … often getting into her lingerie to promote her products or just to feel the breeze on her behind.

Whether it’s all-black undies, or a stylish pair with some color in the shape of rainbows dotting her chest and hips, RiRi always brings her A-game to fashion.

And, occasionally, Rihanna likes to strip down to nothing at all … placing a strategic arm over her nipples to pique the interest of her excited fans.

Rihanna got an early birthday present for her 37th … as you know, her partner A$AP Rocky was found not guilty on two charges of assault with a semiautomatic weapon in L.A. this week.

Rocky dove into Rihanna’s arms after the verdict … and, the two went out and grabbed dinner together in the evening to celebrate.
