LOS ANGELES (AP) - It wasn't ladies night on "American Idol."
The 10 male semifinalists performed Tuesday on the Fox singing competition instead of the 10 female semifinalists because 24-year-old dreadlocked singer Crystal Bowersox from Toledo, Ohio, has "medical issues which would prevent" her from performing, the network said Tuesday.
Fox spokeswoman Jill Hudson would not provide additional details because the network has a policy against commenting on contestants' personal lives. Another person close to the show said Tuesday that Bowersox had been hospitalized for a serious health problem but was expected to perform for viewer votes Wednesday.
The person spoke on condition of anonymity because they were not authorized to comment publicly. Bowersox, a single mother who also plays the guitar and harmonica, pleased the judging panel last week with her performance of Alanis Morissette's "Hand in My Pocket."
Kara DioGuardi told Bowersox she had an ability to take viewers on a journey when she's singing. During "Hollywood Week," Simon Cowell praised the singer-songwriter for being "infectious."
