Lauren Jauregui Debuts Three New Solo Songs at Halsey's Show in Brazil: Watch

Halsey has enlisted Lauren Jauregui as the supporting act for the Latin American leg of her Hopeless Fountain Kingdom World Tour, and just one night in, the Fifth Harmony member is stealing the show. Jauregui gave fans a peek at her forthcoming solo material by debuting three new tracks during her set in Sao Paolo, Brazil Wednesday (June 6), which marked her first-ever solo performance in a concert setting.

Jauregui, who has yet to officially release solo material of her own, showed a range of sonic diversity with the new tracks: the smashing rock jam "Toy," pop ballad "Inside" and R&B-infused slow jam "No Expectations."

"GUYS IM SCREAMING OH MY GOD SEEING ALL OF YOUR REACTIONS TO THESE SONGS AND LITERALLY PEOPLE WERE ALREADY SINGING THEM BY THE END OF THEM I LOVE YOU SO MUCH," Jauregui tweeted post-performance. "Obrigada São Paulo you have my heart forever!! First show ever DONE!!"
