Following her exciting night at the iHeartRadio Music Awards [1], Taylor Swift [2] headed out for a hike in Hollywood on Monday, later enjoying a girls' night with Fifth Harmony's Camila Cabello. The pop star sported short green shorts and a tank top for her hike, carrying her phone and listening to music while she soaked up some sun. That night, she showed off her abs in a black-and-white crop top and a white skirt as she and Camila headed home. Taylor also took to Instagram during their night out, sharing a hilarious video [3] of the pair's reaction after Fifth Harmony's song came on the radio.

Sunday's show and Taylor's performance with Madonna [4] marked the latest in a long list of incredible moments [5] from what's already an exciting year for the star. Taylor is gearing up for her world tour, and last week, she hung out with Calvin Harris in Nashville [6], hitting the stage at Kenny Chesney's concert before joining Calvin in the crowd. Keep reading for pictures of Taylor's LA outings, and then watch a hilarious throwback to the time Ellen surprised her with Justin Timberlake [7] back in 2008.
