Jessica Simpson Flubs Lyrics (Again) At Tour Finale

'I messed up again! I do this all the time!' singer tells Irvine, California, crowd.

While on the road as an opener for [artist id="710215"]Rascal Flatts[/artist]' Bob That Head Tour over the past couple of months, Jessica Simpson has run into her share of snafus, from forgetting lyrics to comments about [news id="1606023"]her weight[/news]. Her last stop on the tour in Irvine, California, was no exception.

According to US Weekly, at Saturday night's show, [artist id="1245169"]Simpson[/artist] messed up the lyrics to "Remember That," a song she introduced at a show two days prior with a few revealing words about abusive relationships. "Oops! I said 'whiskey' too early! I messed up!" she said before starting over. "I'm so embarrassed! But I'm starting over again because I really want you guys to hear the lyrics the right way."

Not only did Simpson mess up the lines to "Remember That," but the singer, who has had to start songs over during previous stops on the tour, also flubbed "Still Don't Stop Me." "I messed up again! I do this all the time!" she said.

Despite the mistakes, Simpson's set wasn't without highlights. She seemed to win the crowd over with her cover of Robbie Williams' "Angels." "I know that we all feel that we have angels around us, watching over us all the time. It's so important to remember that," she told the audience, who erupted into applause at the end of the song, prompting Simpson to joke, "I just felt like I was on 'American Idol'!"

She also dedicated the song "You're My Sunday" to the "person I'm in love with right now," her football-player boyfriend, Tony Romo. She dedicated her last tune, "Come on Over," to country icon Dolly Parton. "It's so amazing to be up here," she said while introducing the song. "I still can't believe I'm here!"
