Taylor Swift shook off a “significant case” of laryngitis to headline the second night of London’s Capital Jingle Bell Ball on Sunday. The singer had a mild hoarseness, but Swift’s energy didn’t seem to dip at all during performances of “Shake It Off,” “I Knew You Were Trouble” and “Blank Space” that have surfaced online. Swift also rocked “We Are Never Ever Getting Back Together” and “Love Story,” closing out a concert event that included performances from Sam Smith, Ed Sheeran, Jessie J, 5 Seconds of Summer, Union J and OneRepublic.

“If you are aware and conscious of the fact that I have laryngitis and am going to need your help singing,” she announced in a raspy voice at KIIS FM Jingle Ball in Los Angeles on Friday night, per Billboard. “But I wasn’t going to miss this. This is the best time I’ve ever had while having laryngitis, I can tell you that.”
