Jessica Simpson was booed during her first country music concert at the weekend.

The 28-year-old blonde launched her new sound at the Country Thunder Festival in Twin Lakes, Wisconsin, on Saturday night (19.07.08) but the show didn't go well.

As well as showcasing material from her forthcoming album Jessica - who was dressed in tiny shorts, cowboy boots and a tight white shirt - also performed covers of country tracks including Willie Nelson's 'On the Road Again' and Shania Twain's 'Who's Bed Have Your Boots Been Under?', but the unimpressed audience heckled the singer throughout.

One spectator, Adam Matos, claimed she "wasn't good enough".

He told the Kenosha News newspaper: "I just don't hear the country in her.  I don't hear the twang. She's not good enough to be here."

Jessica - who is dating American football player Tony Romo - tried to win over the crowd between songs, saying: "I don't know what your perception is of Jessica Simpson or what tabloid you buy, but I just want you to know that I'm just a girl from Texas. I'm just like you. I'm doing what I love and dating a boy."

Critics also failed to be won over by the performance, with one noting: "Many audience members found her attempt to crossover into country irritating and that her vocals lacked a southern sound."

Jessica recently revealed she wants to make country music for "the rest" of her life.
