Taylor Swift Hiking sunglasses singer blonde Ed Sheeran

She's working on her fitness!

Taylor Swift and musician buddy Ed Sheeran decided to get in some good cardio by going for a hike at nearby Franklin Canyon in Beverly Hills on Saturday.

The 23-year-old singer has been doing a great job of staying fit and fabulous, as evident in her look from the Weinstein Company holiday party recently.

Wonder if Harry Style's having any regrets?
