Justin Bieber was seen serenading his wife Hailey Baldwin outside of Buckingham Palace in London on Tuesday.
The 24-year-old pop star told the 21-year-old model that he loved her, then played the guitar as he sang his 2016 hit "Cold Water."
Fans were quick to document the performance and share it on social media.
"So I'm just sitting on a fountain outside Buckingham Palace when some big black cars stop right in front of me and some kid in a pink hoodie gets out with a guitar. Turns out to be @justinbieber and he starts serenading his Mrs," one tweeted.
