On Tuesday, the singer, 24, was spotted singing with a guitar outside London’s Buckingham Palace, where he sang in front of a group of fans that included wife Hailey Baldwin.

Axar.az reports citing People.

In addition to telling the model, 21, that he loves her, Bieber serenaded her with an acoustic version of his 2016 collaboration with Major Lazer and MØ, titled “Cold Water.”

The pop star was dressed in black shorts and a multi-colored tie-dye sweater with the hood over his head while bride-to-be Baldwin wore a matching grey sweatsuit.

The pair, who legally tied the knot in New York on Sept. 13, was also seen walking hand-in-hand and Bieber wrapping his arms around Baldwin after visiting the London Eye.

Meanwhile, that same day, across the pond, Hailey’s uncle, Alec Baldwin, seemingly confirmed the marriage news at the 2018 Emmy Awards in Los Angeles, telling Access: “They just went off and got married.”
