The Miley Cyrus show scheduled for Monday, April 21st at the Wells Fargo Center has been postponed until Saturday, August 2nd.
The Wells Fargo Center says all tickets will be honored on the new date.
Cyrus' show was originally scheduled for Tuesday, April 22nd, but was moved to Monday due to the Philadelphia Flyers Stanley Cup Playoffs game.
A representative says the singer won't perform in Nashville, Tennessee, on Friday and Louisville, Kentucky, on Saturday. Those concerts will be rescheduled.
Cyrus suffered from a sinus infection last week during her "Bangerz" tour. Her rep says she had "an extreme allergic reaction" to the antibiotic cephalexin.
This week, Cyrus also canceled concerts in St. Louis and Kansas City, Missouri. She postponed a show in Charlotte, North Carolina, last week because of the flu.
