Simon Cowell partied with lingerie-clad models at the infamous Playboy mansion on Saturday night. The TV mogul attended magazine founder Hugh Hefner's annual Midsummer Night's Dream party, held at the 83-year-old's Los Angeles home.

Jon Voight, Shaquille O'Neal, Jack Osbourne, James Van Der Beek, Ryan Seacrest, Randy Jackson, Shannon Elizabeth, Jon Lovitz and Hefner's former girlfriend Bridget Marquardt also attended the bash.

Dannii Minogue stopped having Botox so she can get some expression back on her face. The "X Factor" judge has previously undergone the cosmetic procedure - which involves having a series of skin-freezing injections - but is stopping the treatments because it prevents her face from moving freely.

Dannii, 37, said: "I see the comments. Plastic. All Botox. I can see what people see, but I have to say that - while I have been open about doing it before - I'm not doing it now."

Victoria Beckham is set to become a judge on "American Idol." The 35-year-old star has reportedly been approached by the show's producer Simon Fuller - who managed the Spice Girls and is an advisor to Victoria's husband David - about replacing Paula Abdul on the popular U.S. TV series.

Paula revealed she was quitting Wednesday. It is believed she made the decision following a row over pay.

Cheryl Cole is heading for "total meltdown." The Girls Aloud singer is reportedly struggling to juggle her role as a judge on U.K. TV talent show 'The X Factor' with recording her debut solo album.

A source said: "She was given time off from Girls Aloud to have a rest but now she is working harder than ever."

Leona Lewis is having hypnotherapy to boost her confidence. The "Bleeding Love" singer's mentor Simon Cowell has arranged for her to be treated by celebrity therapist Paul McKenna to banish her nerves ahead of her proposed 14-month tour.

A source said: "Seeing as Leona is on the path to becoming a global touring powerhouse, no corners will be cut."
