It seems as if German fans weren’t pleased with the performance delivered by pop star Britney Spears. Their complaints included lip-synching, delays and dissatisfaction with her overall performance.

In addition, the audience was displeased with Britney’s appearance, reportedly calling her nicknames as a result of recent weight gain.

After the concert, Brit headed straight to her luxury suite at the Grand Hyatt hotel, bypassing news agency photographers and disappointed fans. Whatever. They’re probably just pissed she’s a brunette now.
