The wonder of the under boob?? (PHOTOS)

Rihanna showed off the under of her wonder boobs at her recent concert in London. This was reported to not be an intentional slip (like Madonna), but a TRUE wardrobe malfunction (unlike Janet Jackson).

Rihanna was said to be working so hard on stage (in her first concert back since her grandmother passed) that her itsy-bitsy top wandered north. Grams would be so proud. It actually wasn’t really that big of a deal; just a bit blinding.

However, this is not the first time our Barbadian beauty has flaunted her girls’ southern region… Her photoshoot for GQ back in December got pretty racy.

We’re not really interested in the blatant under boob reveals though… We’re more curious about the under boob seemingly being part of a new fashion trend…

Check out some of the stars who’ve incorporated the under boob into their outfits, like they would a scarf, hat or simple silver hoops.
