Rihanna is a sexpot. We know this, as evidenced by the shimmery, sequined cape top she wore while supporting her brother Rorrey at a gig in London on Sunday, June 16.

She went bra-free -- not an uncommon occurrence for our gal. She is also a good sister, taking time out of her busy schedule to brave the public and support her bro.

RiRi hit Boujis in London to take in Rorrey's set, where he performed as Gallest. She partied with her new BFF, model Cara Delevingne, and looked bomb while doing it.

RiRi wore destroyed boyfriend jeans, paired with the cape top. It was a mix of high and low that worked.

She paired the jeans with silver strappy heels and a iridescent envelope clutch. So she was sparkling and shining bright like a diamond.

Cara, who RiRi has referred to as her "lover," was in the hizzy, all casual. She was wearing a bra, since you can see it from the side.

RiRi also spent Monday shopping with her younger bro. They were holding hands -- they must be tight. Check out his Michael Jackson outfit.
