Jessica Simpson or Jaymes? The singer arrived at a Lake Tahoe concert showcasing a curious choice of dress

Stepping out for a concert in Lake Tahoe, the 28-year-old seemed to have left her fashion sense in the Hollywood Hills.

And perhaps the singer realised her mistake once she was in public.

Usually sunny and smiling, she looked distinctly forlorn as she walked alongside boyfriend Tony Romo.

However, poor Jessica has been working hard recently and could be forgiven for her style error considering her packed schedule.

On June 26 she wrote in her blog: 'These past few days I've been in 4 states, on 8 flights, and in 4 time zones promoting my single "Come On Over", and I've had such a great time.'

Perhaps all the graft is taking its toll and affecting her judgement.
