Fans think Fergie 'butchered' the national anthem

Singer Fergie is known for her powerful pitch-perfect voice.

But unfortunately her version of the American national anthem before the start of an NBA All-Star basketball game on Monday left viewers perplexed, with the singer receiving some serious backlash.

Her rendition of Star-spangled banner sounded more like a strangled cat than the national anthem, viewers thought.

Some fans even went as far to say she was drunk during the awkward performance.

Viewers took to Twitter to share their feelings on how Fergie's performance went, and even some of the basketball players couldn't contain their giggles, finding her Marilyn Monroe style performance hilarious and uncomfortable to watch.

Last year the singer opened up about her addiction to crystal meth, revealing the extent of which she depended on the drug and how it left her suffering from serious symptoms of psycosis and dementia.

The 42-year-old singer, who became addicted to the methamphetamine during her time in girl band Wild Orchid, told E News her addiction became so bad she also suffered from hallucinations so bad she was left paralysed with fear.

"At my lowest point, I was [suffering from] chemically-induced psychosis and dementia," Fergie told the outlet. "I was basically hallucinating on a daily basis. It took a year after getting off that particular drug for the chemicals in my brain to settle so that I actually stopped seeing things."

The Glamourous singer struggled with her addiction to meth for a year before leaving the band in 2001, and going on to find fame with the Black Eyed Peas.

Fergie added that while she was in a dark place during that time in her life, the experience gave her reasons to be thankful for her life now.

"I'd just be sitting there, seeing a random bee or a bunny," she added. "The drugs thing, it was a hell of a lot of fun... until it wasn't. But you know what, I thank the day it happened to me. Because that's my strength, my faith, my hope for something better."
