Ida Maria [ tickets ] says she is totally exhausted and will not be finishing her stint on the Perez Hilton [ tickets ] Presents tour, according to a statement on her MySpace page. The Norwegien rocker plans to head home and rest under doctor's care. "After touring in Scandinavia, Europe, the UK, Australia, Japan and the USA for three years straight, I am just completely exhausted," she said in the statement. "I have learned that I am not a superwoman."

Maria reportedly had a mini-meltdown onstage during the tour's Boston stop, walking off after only playing a couple of songs. Her emotional exodus reportedly was sparked by poor attendance; apparently only 250 people showed up to the 2,400-capacity House of Blues.

Natalie Portman's Shaved Head [ tickets ] reportedly will join at least one show on Hilton's tour, which also features Ladyhawke [ tickets ], Semi Precious Weapons and Sliimy.

The next two Perez Hilton Presents tour dates--Monday (9/21) at the Fine Line Music Cafe in Minneapolis and Tuesday (9/22) at Turner Hall Ballroom in Milwaukee--are now free shows. Hilton, who reportedly purchased all of the tickets, is only asking concert goers to say they are a "friend of Perez" at the door to get in for free. Those who have already purchased tickets for those two shows can seek refunds at the point of purchase.

There has been no official word regarding ticket prices for the remainder of the tour, which also features Julian Perretta and Eric Hutchinson on select dates.
