Roseanne's tweet: "Who saw Fergie's national anthem performance at the NBA All Star Game? I think mine was better lowkey." As she explained in 2015:

“I started too high. I knew about six notes in that I couldn’t hit the big note," she admitted. "So I just tried to get through it, but I couldn’t hear anything with 50,000 drunk a--- booing, screaming ‘you fat f---,’ giving me the finger and throwing bottles at me during the song they ‘respect’ so much.”

At TMZ, Fergie explains:

"I've always been honored and proud to perform the national anthem and last night I wanted to try something special for the NBA. I'm a risk taker artistically, but clearly this rendition didn't strike the intended tone. I love this country and honestly tried my best."
