The only thing hotter than the Saint-Tropez sun?!? Latto's latest bikini photos from her super luxurious getaway!!!

The 27-year-old rapper first hit us with the 'turn around, stick it out' shot ... accompanied by another derriere-feature ... all while sailing the French Riviera.

Today, she dropped this biker-babe pic on her social media.

She looks super fine ... accessorizing with a Chanel beach bag ... and a pose that's melting in our memories.

Latto had a baby earlier this year, and she's got the after-pregnancy glow here.

Check out the gallery ... Latto's heatin' up!
