Haha, she sucks…  Really well, I’d imagine.  Grand Rapids Press:

But it was pop singer-turned-actor-turned-country starlet, Jessica Simpson, who generated the most reaction as she fought back tears, forgot her lyrics and mumbled her way through a bizarre 38-minute set.
Almost from the opening song of “These Boots are Made for Walking,” Simpson fought with her ear monitors, constantly trying to keep them in place, meaning she was having difficulty hearing her own voice. That’s frustrating.
At one point she had her backing seven-piece band stop and start over on the uptempoed song “Pray Out Loud.”
After that, she forgot the lyrics to her single “Come on Over,” which left her extremely frustrated, asking for forgiveness from the audience by mouthing the word “sorry” on two large video screens.
The singer said there are times she feels like walking off the stage — “like tonight.” At the end of the song, she thanked her band for “having her back.” And it looked as if she was wiping away tears as she walked off the stage.

Wait.  People actually pay money to see Jessica Simpson “perform?”  And they have to pay for the torture of sitting through Rascal Flatts?  Is she naked?  No?  Is there free sex after the show?  No?  Well what the hell is wrong with people?!
