Billie Eilish has postponed her March tour dates amid mounting concerns over the coronavirus pandemic.

The singer made the announcement via Twitter, writing, “I’m so sad to do this, but we need to postpone these dates to keep everyone safe. We’ll let you know when they can be rescheduled. Please keep yourselves healthy. I love you.”

The announcement affects 11 stops on her North American “Where Do We Go?” tour. Namely, March 13 in Philadelphia; March 15 in New York City; March 16 in Newark, New Jersey; March 18 in Washington D.C.; March 19 in Boston; the 20th in Brooklyn; March 23 in Detroit; March 24 in Chicago; March 25 in Indianapolis; March 27 in Nashville, and March 28 in St. Louis.

The postponement was likely affected by Live Nation and AEG's — two of the world’s biggest concert promoters — decision to halt all large-scale tours until April due to the pandemic.

Eilish is the latest of many artists to call off tour dates, including Stormzy, BTS, and Mabel.
