Lori Harvey‘s bringing the heat to Mexico … flaunting her flawless bikini body in some sexy snaps from a vacation south of the border.

The model just shared a bunch of photos from her trip to the One&Only Mandarina in Nayarit … a super expensive and exclusive oceanfront resort.

We broke the story … Lori jetted down to Mexico with her ex boyfriend Damson Idris in tow … and it looked like they may be giving their relationship another shot.

Still, that means we get plenty of Lori photos to enjoy … with a couple mirror selfies to boot.

The resort looks good, but Lori looks better … so be sure to click through the gallery.
