Check out the video above to see him serenading her and Hailey filming it all (very relatable, we'd do the same). The singer showed his love for her today in front of a crowd with a public performance outside the Buckingham Palace in London. The newlyweds are in England this week for Baldwin's runway appearance with Adidas Originals in the Falcon Catwalk Show.  

A witness who saw the couple in London confirmed their PDA and told E! News that "they were very affectionate, stopping on street corners to pull each other in close to kiss".

People on Twitter are absolutely freaking out about the singer's special appearance in London and his singing tribute to his new wife, Hailey Baldwin. Lucky bystanders posted videos of the singer busking and gushed about how sweet the whole encounter was, and others were so shook that they missed it. Check out some of the reactions below:

But before we talk about how sweet and romantic the whole serenade was, let's take a walk down memory lane here. This isn't the first time the singer has publically serenaded his love. Justin Bieber did the same to Selena Gomez, two years ago. Looks like the Biebs has a few romantic tricks up his sleeve. 

This serenade happened in November 2015 also made headlines and was in a public space, taking place in a hotel bar. Justin Bieber is famous for his voice, so it makes sense that he uses it to his romantic advantage. 

Stay tuned for more news on the couple cause we're sure that Justin Bieber and Hailey Baldwin will be making headlines again soon.
