Taylor Swift & Ellie Goulding Burn Down London Before Chopping Off Her Hair! Watch Their Duet HERE!

Seeing as how oxygen is highly flammable, there’s probably no better place to sing Burn than the O2 Arena!
Maybe that’s why Taylor Swift decided to close out her series of packed shows at the London concert venue by duetting with Ellie Goulding!
But this isn’t just her final performance at the O2- it’s her final performance before chopping off that gorgeous blonde hair!
See the fiery duet and get a last look at those locks …AFTER THE JUMP!!!
