The singer had to cancel a promotional trip to Europe and a performance at the World Music Awards in Monaco earlier this month due to illness. Now, she’s back on schedule and should be in top form for her May 19 show in Holland, Mich., and May 20 concert in Omaha, Neb., according to her official Web site.

Additionally, new dates for her first full-scale, headline tour have been released.

Fans out west can breathe a sigh of relief knowing the teen queen isn’t going to overlook them on this outing. Aguilera will stop in Denver, Colo.; Salt Lake City, Utah; Phoenix, Ariz., and points up and down the Pacific Coast during October.

The 60-city tour starts July 1 in Milwaukee, Wis., and ends October 15 in Phoenix.
