Ashlee Simpson's Big Comeback

Pop princess Ashlee Simpson, who recently turned 21, has dealt with her share of drama in the past year, including a lip-synching snafu on "Saturday Night Live."

But she's come through those trying times and released a new album called "I Am Me," with songs that she says are about "finding the positive and lighter side." The album is available in stores today.

Simpson performed her new single, "Boyfriend," and "Coming Back for More," also from the new album, on "Good Morning America" today as part of the Women Rule concert series.

'SNL' Redemption

Simpson returned to "Saturday Night Live" on Oct. 8 to redeem herself after last year's disastrous appearance, when she was caught using pre-recorded vocal tracks and fled the stage. She later claimed to be suffering from acid reflux.

"It was amazing," Simpson told "Good Morning America." "I honestly felt so confident and so relaxed."

Simpson sang a new song, "Catch Me When I Fall," on "SNL," telling the audience, "I wrote this song after my last 'Saturday Night Live' appearance."

By most accounts, her "SNL" performance was a success this time around. "I Am Me," with 11 songs co-written by Simpson, has also been well-received by critics.

Simpson has also gone back to her blond roots. After a stint as a brunette, Simpson has gone back to being a blonde, like her older sister, Jessica.

"I've always been blond so it's good to go back," she said on "GMA."
