Proving their friendship extends to the outdoors, Taylor Swift and Ed Sheeran shared on Instagram a candid video of the two superstar artists going on a hike on Wednesday — and struggling a bit to catch their breath while on their wilderness jaunt. At the start of the short video Taylor asks Ed, “You OK, bro?” — to which Ed can only respond with a very cheeky hand gesture. She adds later, “It’s called exercise. Have you ever done cardio? Strumming a guitar doesn’t count.”
