Lady Gaga, Rihanna, and Miley Cyrus have been walking around nearly nude lately. The trio joined forces in support of the bra as shirt movement.

The "We Can't Stop" singer dropped by "Good Morning America" on July 15. Miley Cyrus couldn't help but show off her twerking bod in a bra top and skirt. As revealing as the perforated, black-and-white outfit was, it left more to the imagination than Miley's previous outfit. The 20-year-old arrived at the "Good Morning America" studios in a seemingly conservative, ribbed dress with white cuffs and a high neckline. But, wait, Miley forgot her bra! Just when everyone thought Miley Cyrus was keeping her bra size under wraps this time, the former "Hannah Montana" star fooled them all by going bra-less.

Rihanna has never been shy about showing her body. The "Pour It Up" singer can't seem to help herself. Rihanna's latest in nearly nude, bra-as-shirt looks had her onstage at the Yahoo! Wireless Festival in a leather bralette, shopping in Monaco in nothing but a swimsuit, and dining out in an Alexander Wang bra top. Just like Miley Cyrus, Rihanna also goes by the bra only, or no bra at all rule. Case in point: Rihanna at Chanel's Paris fashion show in nothing but a long, cream cardigan. The Bajan talent just likes to let loose.

Lady Gaga's bra during her New York City errand run got the bra-as-shirt ball rolling. But Lady Gaga's lace demi cup is only one among her arsenal of interesting street wear that often involve elaborate wigs and questionable footwear. The "Artpop" singer, free of her wheelchair, with her bare face in sunglasses, wearing a black bra, skirt, and black boots almost looked...normal.

Here's to hoping this bra trend starts and ends with Lady Gaga, Rihanna, and Miley Cyrus!
