Ed Sheeran, Macklemore Perform Gay Marriage Anthem 'Same Love'

Macklemore joined English singer-songwriter Ed Sheeran to perform the hit gay marriage anthem Same Love over the weekend at the iHeartRadio Festival in Las Vegas.

The 23-year-old Sheeran quietly began with the song's hook – “I can't change, even if I tried, even if wanted to. My love, she keeps me warm” – then asked the audience to welcome Macklemore to the stage.

“Make some noise for Macklemore!” Sheeran told the audience.

“SURPRISE!!!!!” iHeartRadio tweeted. “@macklemore joins @edsheeran on stage for #SameLove at the iHeartRadio Music Festival.”

After the performance, Macklemore messaged: “Huge thanks to my brother edsheeran for bringing me out tonight at the @iheartradio festival in Vegas! I'm very grateful to be a part of his set. … Now it's time to lose some money! I'm spending Ed's paper.”

“Much love to @macklemore for hopping on stage with me tonight,” Sheeran tweeted.

A Grammys performance of Same Love featured Queen Latifah officiating over the weddings of 33 couples, some of whom were of the same sex. While Macklemore & Ryan Lewis took home four prizes that night, Same Love lost the award for Song of the Year to Royals by Lorde.
