Ashlee Simpson spent much of Monday night and Tuesday morning making light of, and poking fun at, the media hoopla that has surrounded her lip-synching miscue on "Saturday Night Live."

"It's so silly that everybody's concerned about this one performance when there's so many things going on in the world," she told MTV News Tuesday morning, after her appearance on the "Today" show. "We have an election, there's people dying — and people are concerned if I can sing or not. You hear me sing on my reality show every day."

Still, she gets the humor of the situation, and although it's embarrassing to her that everyone's focusing on her very public slip-up (see "Ashlee Blames Gastric Distress For 'SNL' Lip-Synch Snafu"), she said she's laughing with everyone that's laughing at her.

"I think I'm getting through this by being completely honest," Simpson said. "I think the truth is the best thing, laughing about it and, you know, making light of the situation. Maybe ['SNL'] will spoof me or make fun of it, and I'm OK with it, you know?"

Before "SNL" was able to take a shot at her, though, she took one herself. At the beginning of her performance on NBC's Radio Music Awards Monday night, in which she was scheduled to perform her new single "Autobiography," her band started to play "Pieces of Me" — as they mistakenly had on "SNL." Simpson cut them short, yelling in mock horror, "Wrong song!" Then she turned to the crowd and laughed, "Just kidding, you guys!" before launching into an unmistakably live version of "Autobiography."

"I was really happy about last night," Simpson said. "It was really nice to get out there and perform. There was definitely pressure, because, you know, everybody is looking: 'What's going to happen? Is she going to croak? Is she going to mess up?' I just had to block it all out and focus on the positive. It was a nice place to actually get to redeem myself."

Still, she said, she understands the concern, and wants to reassure her fans that the "SNL" incident — in which she had used a backing track because her voice was giving out — was not going to be repeated, even if she is sick again in the future. She said this was the first time she had ever relied upon a backing track, because although it's a common music industry practice, she prefers to sing live, "from my heart." She reiterated that she thought if she didn't use the track, she would be damaging her vocal cords.

"I don't think I'll ever use a guide vocal ever again," Simpson said. "I didn't want to use a guide vocal, but everyone was like, 'You have to.' Like, I couldn't talk, like I really couldn't speak. I hope that I never ever, ever, ever, ever have to use a guide vocal ever again. I don't think I would anyway. I just wouldn't do the show."
