Rihanna‘s not exactly known for her conservative wardrobe, but she took it to a whole new level Feb. 10 at the 55th Annual Grammy Awards. RiRi stepped out in a custom Alaia gown that not only showed off her enviable curves, but her nips as well!

But RiRi didn’t just put on a show on the carpet; she also took to the stage later in the evening. She was one of several performers — Bruno Mars, Sting, Ziggy and Damian Marley were also on the bill — who paid tribute to the late, great Bob Marley.



Of course, Rihanna wasn’t the only celeb to ignore Grammy producers’ wishes. Tons of stars stepped out in skin-baring ensembles, and of course, HollywoodLife.com would like to take time to salute them all.

Jennifer Lopez, who basically pioneered sexy Grammy dressing back in 2000, showed up with her entire right leg on display, Angelina Jolie-style. (Has someone made a Twitter handle for that thing yet? Seriously.)

And Kelly Rowland — fresh off her buzz-worthy performance with Beyoncé and Michelle Williams at the Super Bowl — showed off crazy amounts of boob and general skin in a zig-zagged cut-out dress.

Natasha Bedingfield and Ashanti both rocked major sideboob, as well.

And then there was Katy Perry, whose boobs were just chillin’ front and center the whole night.
