Rihanna surprises crowd, 'shines bright like a diamond' at 'We Can Survive' concert

It was a night of throwbacks and booty shakin' anthems at CBS Radio's "We Can Survive" benefit concert Saturday night at the Hollywood Bowl. The third annual show aims to increase breast cancer awareness with this year's proceeds going toward the Young Survival Coalition.

The boys of 5 Seconds of Summer gave us a sneak peek of their set during soundcheck where fans screamed at the top of their lungs and even sang along to tunes from their newest album, "The New Broken Scene," that was just released a day prior to the event -- confirming that 5SOS fans may be the most dedicated yet!

Demi Lovato got the party going with her summer anthem, "Cool For The Summer" and tour buddy Nick Jonas got everyone on their feet with his smash hit, "Levels." The night was just getting started as a sea of neon lights lit up the Hollywood Bowl, jumping and swaying to the catchy tunes of the former Disney star. Jonas closed out his electrifying set with a cover of Bell Biv DeVoe's "Poison," and set a dance party tone for the rest of the night.

As if they night couldn't get any better, Grammy winner Sam Smith gave an emotional and powerful performance of his smash hits, "I'm Not the Only One," and "Stay With Me." Smith dropped a major bombshell revealing that this would be his last U.S. performance and was heading to the studio to record his second album.

Maroon 5 gave everyone nostalgic feelings when they performed their classic "This Love" and "Sunday Morning," proving they haven't forgotten about their edgy-yet-sensitive roots.

DJ Calvin Harris revived the crowd with his electro-pop dancing anthems, escalating the crowd's energy and then in true EDM-style, dropped the bass down real low with "Feel So Close."

The headliner of the night, The Weeknd, did not disappoint with an explosive version of his current smash hit, "Can't Feel My Face" and then literally set the stage on fire with his dark and evocative track, "The Hills."

But the show was not done!

The biggest surprise of the night was special musical guest Rihanna who donned a pinstripe coat and lace bustier, setting the crowd in a frenzy with her hit "B*tch Better have My Money." She closed the incredible night with a beautiful rendition of "Diamonds," proving that our favorite bad gal still has what it takes to take an audience from booty shakin' to crying their eyes out.
