At her August 26 show at the Staples Center in Los Angeles, Taylor was joined onstage by her “BFF”Selena Gomez to perform Selena’s summer hit “Good For You.” The Internet later exploded with photos of the two friends looking sultry in body-baring ensembles – Taylor flaunting her toned stomach in a white crop top, and Selena showing off her cleavage in a plunging neckline. Both wore thigh-high boots as they strutted all across the stage. Selena later took to Twitter to share photos of the duo performing together back in 2011, noting she had “all the feels” following their latest performance. She also wrote, “So grateful. Tonight was so special.”
