She could have had a wardrobe malfunction at any moment, which is why Rihanna must have needed pal Katy Perry to have her back - or her front, as it were.
The blue-haired pop star made sure that her longtime pal hadn't popped out of her dress at the 54th Annual Grammy Awards tonight.
It would have been quite easy for the 23-year-old Bajan singer to shimmy out of her slinky black Giorgio Armani gown.
The We Found Love singer wore a slew of Neil Lane jewels, including a diamond and gold snake amulet, a gold cuff, gold and diamond rings as well as gold triangle earrings.
She also wore a strategically placed gold body necklace, as well as sexy Christian Louboutin heels and a matching Jimmy Choo clutch.
