While she can relate to the pressures of learning how to play live and work an audience for the first time, Avril Lavigne says she takes exception to the practice of lip-synching, which has been in the news thanks to a slip-up during Ashlee Simpson's appearance last weekend on "Saturday Night Live."

"You know what, there are a lot of people out there today, who have become stars or famous musicians -- I wouldn't really define them as a star -- with a record only because they have connections and only because they have money and for the wrong reasons," Lavigne tells Billboard.com. "And it sucks. Actually, I know for a fact there are some young female artists who don't even sing on their own records and who don't sing live. And that is pathetic."

She quickly adds, "I got signed because of my voice. That's what [Arista head Antonio] 'L.A.' Reid signed me on. He said, 'Wow, you are only 15 and you can really sing. I'm going to sign you.' And I've never lip-synced once."

Lavigne is in the midst of a North American tour that drops in on Hampton, Va., tomorrow (Oct. 30), and the artist says she's more confident than ever. On stage, she's singing, playing piano and even showing off her drum chops on one song.

While she admits she's been doing a little writing on tour, and live material is being gathered for an eventual DVD release, there is no timetable for her next project. Says Lavigne, "No, I'm going to be out here for a while."

As previously reported, the artist recorded the theme song for the upcoming "SpongeBob SquarePants" soundtrack, due Nov. 9 via Sire.

"I sang the theme song but did my own version for the movie," she says. "I had never done anything like that before so I said that would be kind of cool. You know, a good experience. I just did a rockier version -- a me version of it."
