Shawn was all smiles as he performed some of his biggest hits on Tuesday night. The "In My Blood" singer opted to wear a maroon colored button-down shirt with the sleeves rolled up to show off his strong forearms.
He completed his look with a pair of dark denim jeans and a silver watch.
Sabrina stunned on stage wearing a black two-piece set underneath a see-through black lace dress and added knee-high leather boots. She kept her long blonde locks down in loose beach waves and looked gorgeous with a minimal but glamorous makeup palette for the concert.
Before her performance, the "Almost Love" pop star was photographed backstage wearing a red jumper and some pointed nude heels.
Calvin also performed last night and was seen backstage doing an interview. He was wearing a black graphic tee with black denim jeans and grey sneakers.
