Usher threw the party of all parties on Monday, October 17, 2005.
The singer took over the historical Roosevelt Hotel on Hollywood Boulevard to celebrate the launch of his new three DVD set 'Truth Tour' and, belatedly, his 27th birthday, which was last Friday. Hundreds of A-list celebrities from the music and film world were invited to help the Grammy winner celebrate his double whammy.
The DVD set, which is only available at Best Buy stores, contains five hours of footage from Usher's hometown Truth Tour performance in Atlanta, an in-depth view of his life so far, as well as a fly on the wall look at the charity work he's been doing.
The guest list included former boxing champion, Mike Tyson, jazz great, Herbie Hancock, Lindsay Lohan, Paris Hilton, Ryan Phillipe, Eliza Dushku, Emmanuelle Chriqui, The Pussycat Dolls, Fergie and Will.I.Am of The Black Eyed Peas.
