US songstress Taylor will be joining singing sensations Ed and Sam, as well as boyband of the moment 5SOS on Sunday 7 December for the second night of the music extravaganza in London.
Joining them at the Capital Jingle Bell Ball with Morrisons will be Jessie J, Rixton and Fuse ODG.
Chart-topper Taylor, who recently announced UK tour date for 2015, said: "I love Christmas and I am so excited to be performing at this year's ball. I hope Capital listeners are ready to party with me!"
Meanwhile Ed, who has previously toured with Taylor, is hoping to have some company in his dressing room!
"I'm really looking forward to performing at Capital's Jingle Bell Ball," he said. "But I have one request - I'd like puppies for my dressing room! I'd like at least one - someone at Capital must have a puppy they can bring for me!"
You heard him, Ed wants some puppies!
