 Fox's Jeff Manasso at the convention in Milwaukee. A public apology from the singer who opened baseball's home run derby last night. Country singer Ingrid Andrus says she was drunk during her performance of the national anthem during MLB's home run derby on Monday. The 32-year-old posting on her social media that she will be checking into a rehab facility to get the help she needs. Adding, quote, that was not me last night. I apologize to MLB, all the fans, and this country I love so much for that rendition.
