CBS Radio 99.7 NOW!'s Poptopia delivered some big pop sounds over the weekend as the likes of Taylor Swift and Ed Sheeran descended on San Jose, California.

In addition to the two superstar headliners, The Chainsmokers, Dua Lipa, Fifth Harmony, Logic, Niall Horan and Khalid also performed as part of the holiday concert, which was held Saturday night at the SAP Center.

For Swift, it was part of her return to the live stage, marking her second public show after performing a day earlier at KIIS FM's iHeartRadio Jingle Ball show in Los Angeles.

While she and Sheeran both performed separately, the two friends also couldn't resist the chance to offer fans a live rendition of their new collaboration "End Game," from Swift's new album Reputation. The album version also features Future.
