Country music artist Ingrid Andress wrote on social media Tuesday that she was drunk while singing the national anthem at MLB's Home Run Derby on Monday and that she's checking herself into rehab.

Ingrid's off-key rendition that led into Monday's Derby immediately became the subject of jokes and criticism on social media. The following morning, she posted an apology to MLB and fans on multiple social media platforms, declaring, "I was drunk last night."

Andress, 32, is a four-time Grammy-nominated singer and songwriter. She was nominated for Best New Artist, Best Country Song and Best Country Album in 2021 and for Best Country Duo/Group Performance in 2023 for her single "Wishful Drinking" alongside Sam Hunt. She's an accomplished songwriter for performers across multiple genres, with credits including Charli XCX's pop hit "Boys" and Halestorm's "Conflicted."

Andress' performance Monday was off-key from the open and drew ridicule inside and outside Globe Life Field.

Andress performed in the midst of promotion for her new song, "Colorado 9." She announced the single Monday ahead of her performance, along with a scheduled July 17 show in Nashville and another July 24 in Denver. On Tuesday, links to ticket sales for both shows displayed messages that tickets were not available.

Variety reports that in a letter to fans on Monday announcing the single, Andress wrote that she had suffered from depression since the dissolution of relationships with people involved in her career and that she had recently found peace while returning to her native Colorado.
