He stopped to play for his fiancee, Hailey Baldwin.
While visiting London, Justin Bieber took a moment in front of Buckingham Palace to play some music for his fiancee, Hailey Baldwin. As one might expect of a pop-star playing on tourist-filled streets, he drew a crowd.
Christian Headlines notes that Bieber played three songs: “Fast Car” by Tracy Chapman, “Cold Water” by Major Lazer and himself, and “Good Good Father,” a worship song by Chris Tomlin, which one onlooker caught footage of.
