Amidst potential relationship rumours, singer-songwriter Camila Cabello showered some love on Shawn Mendes as she attended his concert at Staples Center in Los Angeles.

Posting a video on her Instagram story from inside the stadium, Cabello wrote, "@shawnmendes you couldn't be more amazing. Wow [red heart emoji,'" and "You're unreal. @shawnmendes."

However, Cabello did not perform with Mendes at the show on Friday.

Mendes is scheduled to perform another show at Staples on Saturday.

Cabello and Mendes were photographed on a night out, hand-in-hand. The pair was also spotted chatting on a balcony.

Also, they were seen together at a Fourth of July party.
