As the band played "Fix You", a fan proposed to his girlfriend and fortunately she said yes, but not without a playful push for the surprise, reported Digital Spy.
After someone shared the video, his fiancee had one request: "Please share as much as possible - we want them at our wedding."
Coldplay paid tribute to the late Labour MP Jo Cox during their show on Thursday and to victims of the Orlando shootings.
"None of us are entirely sure why that stuff goes on. All we can do is send our love out and hope everyone is able to recover," the band said.
