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.

Jon Voight thinks Megan Fox is as "sexy" as his daughter Angelina Jolie. The Hollywood veteran - who has been estranged from the 34-year-old star for several years - thinks recent comparisons between the "Transformers: Revenge of the Fallen" starlet and Angelina are fair because they are both stunning women.

He said: "Everybody is unique. They're both very beautiful and they're both kind of sexy girls."
