LAS VEGAS — What happens in Vegas doesn’t stay in Vegas.
Videocameras descended upon Sin City for the iHeartRadio Music Festival, which was pre-taped over the weekend for its Sept. 29 and 30 broadcast on The CW.
Once televised, the festival will treat viewers with exhilarating performances from radio stalwarts like One Direction, Lorde, Ariana Grande, Calvin Harris and Usher.
Among the most memorable moments: Ed Sheeran teamed up with Macklemore on LGBT anthem “Same Love;” Taylor Swift teased her upcoming album with “Shake It Off;” Nicki Minaj and Iggy Azalea brought rap flavor to the otherwise pop- and rock-heavy event; and Coldplay and Train reminded us why we’re Generation Selfie.
Mashable attended the festival to bring you a sneak peek at what you’ll see. So set your calendars because these are 15 moments you won’t want to miss on TV.
1. Ed Sheeran Duets With Macklemore on ‘Same Love’
Ed Sheeran kept his set simple filling the stage with just himself and his guitar to show off songs from his recent chart-topping sophomore album, X. But unexpectedly, the British crooner brought out Macklemore to tag-team on “Same Love,” the “Thrift Shop” rapper’s LGBT anthem that’s typically performed by Macklemore, Ryan Lewis and Mary Lambert.
2. Coldplay and Train Infuse Their Sets With Seflies
What do you do when your audience begs you for a selfie while you’re performing onstage? Well, if you’re Chris Martin of Coldplay or Pat Monahan of Train you grab their phones, grant their wishes and show them how a celebrity selfie is really done.
3. Paramore Lets Young Fan Sing ‘Misery Business’
Hayley Williams of Paramore invited a fan to belt “Misery Business” (see 4:00 mark in the video, above) She gave the fan, Mariah, some solo time to shine before joining her for the head-banging chorus.
4. Taylor Swift Reminds All of Us About ‘1989’
Can you guess what year Taylor Swift was born by just watching that Instagram? Ding, ding, ding. 1989 is correct and it’s also the title of her upcoming pop album. Swift, who opened the entire festival with an impressive medley of hits as “1989” flashed in the background, closed her set with the album’s lead single, “Shake It Off.” Swift also performed a slowed-down, dramatic remix of “Love Story.”
5. Pete Wentz ‘Crowd Surfs’ on Inflatable Raft
Pete Wentz of Fall Out Boy surfed amid the crowd inside an inflatable boat, high-fiving fans on his way back to the stage during Steve Aoki’s set.
6. Usher Lights Shoes on Fire With Chris Brown
One way to heat up a dance-off against surprise guest Chris Brown is to light your shoes on fire. That’s what Usher did during their duet of “New Flame.”
7. Nicki Minaj: ‘They Deserve to Be Shitted On’
“Anaconda” rapper Nicki Minaj paused her booty-shaking routing to deliver some words of wisdom: “If you’ve got somebody in your life that don’t want to see you shine, put your number twos in the air ’cause they deserve to be shitted on.”
8. Zac Brown Band Covers ‘Bohemian Rhapsody’
The Zac Brown Band incited one of the biggest sing-a-longs of the weekend with an intriguing cover of Queen’s “Bohemian Rhapsody.”
9. Steve Aoki Throws Bakery Cake at Fans
Like clockwork, electronic house musician Steve Aoki once again hurled a bakery-style cake at some rowdy fans. No champagne showers this time, though.
10. Alicia Keys Puts Baby Bump on Display
When he wasn’t lighting his shoes on fire, Usher was spotted backstage playing with 8-months pregnant Alicia Keys’ baby bump, which graced the stage during her inspiring performance of “We Are Here.”
11. Ariana Grande and Childish Gambino Join Forces
Childish Gambino hopped onstage during Ariana Grande’s set to perform “Break Your Heart Right Back,” their duet that samples Notorious B.I.G.’s “Mo Money Mo Problems” and Diana Ross’ “I’m Coming Out.”
12. Weezer Jams Out With 4-Man Drum Segment
Representing the alternative rock genre, Weezer closed their set with the 1994 classic “Buddy Holly” and a 4-person drum session.
13. Lorde’s Hair Flips Out
Are you OK, Lorde? Just kidding. We know you give it your all with your vocals and free-spirited, manic moves — but apparently your hair has a life of its own, too.
14. Jennifer Lawrence Supports Chris Martin
With dating rumors between Coldplay’s Chris Martin and actress Jennifer Lawrence already aflame, J-Law added some gasoline to the fiery rumors by being spotted backstage the same night night Coldplay performed. Consciously coupled. That’s still unofficial.
15. Ed Sheeran Takes Us Back With ‘No Diggity’
In a soulful mashup, Ed Sheeran smoothly blended his new single “Don’t” with Blackstreet’s “No Diggity” and Chris Brown’s “Loyal.”
