We’re back with the 2018 iHeartRadio Music Awards and our fifth year is going to be no less entertaining than previous ceremonies. With the announcement of the forthcoming show as well as this year’s batch of nominees, we thought it’d be fitting to take a stroll down memory lane and revisit some of the most notable moments from yesteryears. From Rihanna’s trendsetting hair, which went viral on the blogosphere, to Taylor Swift and Madonna’s historic onstage collaboration, there are plenty of highlights to look back on.

It's one thing to premiere a new song on the radio, it's a whole other thing when you're helping premiere a Michael Jackson record with a special dance tribute. Usher did just that in 2014 when he offered the crowd a choreographed number to the King of Pop's posthumous release "Love Never Felt So Good.” Plus, it's not like Ursh doesn't consider MJ one of his idols. Back in 2011, he even danced with the legend during a collaborative performance of "You Rock My World.”

Jason Derulo also played double duties during the 2016 affair when he hosted and performed "Swalla." Oh, and do you remember when he stage dived?" "I'm not really the crowd surfing size. I feel like there's a weight limit, and I think I passed that, because I felt like a little cave-in when I landed,” he admitted later on. “But all in all, I was still safe. I was good, but a couple fingers might've been broke. It was a little scary when I did it, though."
