Singer Ingrid Andress says she was drunk during criticized MLB anthem performance, will get treatment

After a widely panned performance of the U.S. national anthem at the MLB Home Run Derby, country singer Ingrid Andress apologized Tuesday and said she was drunk.

"I'm checking myself into a facility today to get the help I need," she wrote in an Instagram post. "That was not me last night. I apologize to MLB, all the fans, and this country I love so much for that rendition."

The MLB is not commenting, spokesperson Matt Bourne said.

A representative for Andress said there will be no additional comment at this time.

On Monday night, the four-time Grammy nominee belted an a cappella version of The Star-Spangled Banner, an incredibly challenging song to sing. Clips of her less-than-popular rendition at the Globe Life Field in Arlington, Texas, went viral.
