Katy Perry has been forced to postpone two upcoming shows due to food poisoning.

Yahoo reports that Perry was under the weather last night during her performance at Milwaukee’s Summerfest festival.

Apparently it hasn’t gotten any better since and her July 8 and 9 concerts have been moved to August. Perry turned to Twitter earlier today to apologize for the switch-up and announced the new dates.

“Chicago and St. Paul—I’m so sorry to have to postpone today and tomorrow’s shows,” she writes. “But I’ll be back 8/21 (CHI) and 8/23 (St. Paul)!”

Pop starlets haven’t been doing so well in the health department as of late. Taylor Swift just canceled a show because of bronchitis, and Adele’s just getting back on her feet after being sidelined by laryngitis.

EW sends its best wishes, and recommends a personal chef, some Robitussin, and green tea, respectively, for these three ladies.
