Beyonce Knowles reportedly had Lindsay Lohan thrown out of her own dressing room because the singer wanted it for herself.

The former Destiny's Child star was performing at the F1 Rocks concert in Singapore over the weekend and had ordered her entourage to get her the largest dressing area backstage.

However, Lindsay - who was hosting the event for British TV network Channel 4 - had already claimed the room for herself as she arrived before and was left upset when she was told she would have to vacate it.

The 'Mean Girls' actress told Britain's Daily Mirror newspaper: "I've been a bit down. It was a strange night. Everyone was being aggressive and bothering me. I really didn't like it."

In the lead up to her performance, Beyonce made her support acts sweat as she wouldn't allow them to use her air conditioning.

Although temperatures backstage approached 90 degrees and people were passing out, Beyonce's entourage refused to switch on her personal air cooling fans as they were just for her.

British DJ Seb Fontaine - who suffered heatstroke - told Britain's Daily Star newspaper: "We were told, 'No they are Beyonce's fans.' I wasn't asking to play her drum kit on stage. I just wanted to keep cool."

In her 139-page rider, Beyonce also demanded six beauty chambers, fitness equipment, an authentic fruit platter and tea and honey.

Other acts to perform at the event - which took place at Fort Canning Park - included Black Eyed Peas and Gwen Stefani.
