The 31-year-old was strutting her stuff in an Adam Saaks swimsuit. His pieces often feature strategic cutouts defined by small pieces of fabric covering the necessities. Basically, they're great for the runway, but not necessarily ideal for a day of frolicking on the beach.
Either way, Brittny seemed pretty happy about her choice of swimwear, even when things got a little sloppy.
In fact, in a video obtained by TMZ, she appeared to be trying very hard to make her wardrobe malfunction worse by pulling on her thong (ouch!) and making sure her butt was in full view...although none of her fellow beach-goers seemed to notice.
She also proudly posted the butt-baring pics on her Instagram page with the caption "out #miami till next time."
Yeah, we definitely tend to prefer the classy, glammed-up version of Brittny G, so hopefully "next time" isn't for quite some time.
