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.

Avril Lavigne was reportedly seen flirting with another man in the lead up to her split from husband Deryck Whibley.

The 'Girlfriend' singer - who announced she was separating from the Sum 41 rocker last week - spent a month partying on oil heir Brandon Davis' yacht in St. Tropez, South of France, and sources say the pair have grown very close.

Lindsay Lohan has denied reports she has been admitted to a psychiatric hospital.

The 'Mean Girls' actress has laughed off rumors she is mentally unwell, adding it was one of the few things she had never previously heard said about herself.

Nicole Richie, Lindsay Lohan and John Mayer were among mourners at a memorial service for DJ AM Thursday. The stars - along with Lindsay's girlfriend Samantha Ronson, socialite Nicky Hilton and actor Eric Dane - gathered with family and fans at the Hollywood Palladium to pay their respects to the musician, real name Adam Goldstein, following his death last week.

An onlooker said: "The crowd was very hip and eclectic, there were people dressed in smart black suits and people dressed in jeans and T-shirts. It was packed though, you could tell how well loved he was.
