"It's so much fun especially when she's there," the "22" singer said of spending last night at the Billboard Music Awards with her bestie. "It turns into sort of a dance party situation and we don't like to think of these things as pressure, like 'Oh, my God, everybody's watching, how do you act?' We just act like we do in our kitchen.
"It was a blast," Swift continues. "It's always so much fun when she's a part of the whole scenario."
Also by Swift's side last night was her English singing buddy, Ed Sheeran.
"She likes cooking and I like eating, so it works out," Sheeran said of touring with Ms. Swift.
Any favorite dishes? "Stir fry," Sheeran said. "That was good. She gets her wok on."
Swift said, "I cook for my friends all the time, and I'm really glad I got like a four-star culinary review there. That's excellent!"
We could only imagine what Swift will be whipping up at her new $17 million estate in Rhode Island.
"She must have a housewarming at some point," Sheeran said. "I'm going to make a wooden sign and bring it there and stick it on a door and claim a room."
With seven bedrooms in the 11,000-square-foot mansion, he should have no problem finding some space.
