A substitute teacher sang Britney Spears’ ‘Toxic’ on a karaoke machine. He was asked to leave early.

A Texas substitute teacher was asked to leave early after singing Britney Spears’ “Toxic” on a karaoke machine he brought to the classroom. 

According to KXAN, the substitute was asked to leave Friday after he was recorded by students at a high school in Austin’s Independent School District. A spokesperson from the district told KXAN the substitute “wasn’t following [the district’s] best practices”

“I’ve heard worse Britney Spears covers, but the lights are a bit much,” an AISD spokesperson told the outlet.

USA TODAY has reached out to the Austin Independent School District for comment.

In video obtained by the New York Post, the substitute appears to be harmonizing with a microphone attached to a karaoke machine that had multiple lights. He then proceeds to sing the rest of Spears’ 2003 Billboard top 10 hit.

“I’m addicted to you, don’t you know that you’re toxic,” the substitute teacher belts out. 

District administrators told the KXAN that the man was a registered substitute teacher in the district who was placed at school to cover a class. 

The substitute performed another song before being “relieved of his duty.” He later picked up another job at the Austin High School AISD confirmed to KXAN.
