Taylor Swift always makes headlines with incredible guest appearances at her concerts, but this weekend her buddy Ed Sheeran had a simliar experience.

Performing his biggest show to date at Foxboro's Gillette Stadium on Friday, Ed Sheeran was joined on stage by Chris Martin of Coldplay for two songs.

The Brits tackled Ed's hit song 'Thinking Out Loud' with Chris on piano and Ed harmonizing and playing acoustic guitar. They also performed Coldplay's 'Yellow,' after which Ed shouted, 'You made my dreams come true, man! Thanks a lot,' before Chris ran off stage.
