Los Angeles, March 20 - It was a busy day in Los Angeles. A musical contingent including Canadian popsters Simple Plan, British R&B sensation Big Brovaz and American Idol’s Ruben Studdard turned out for the premiere of Scooby Doo 2: Monsters Unleashed. The film’s stars husband and wife Freddie Prinze, Jr. and Sarah Michelle Gellar, Matthew Lillard, Alicia Siverstone, Linda Cardellini and Peter Boyle were greeted by lots of tots getting a preview before Friday’s opening.

Studdard had to make a quick change, because he had to get over to the L.A. International Cultural Center Theater, where he and Usher, Nelly, Michelle Williams, Jermaine Dupri and others performed at the 2004 Soul Train Music Awards. R. Kelly, Janet Jackson, Outkast and Beyonce Knowles were honored this year. Judging by her very revealing dress, Ms. Jackson apparently hasn’t been humbled by her Super Bowl boobgate. Later, at Morton’s, Jackson wore jeans to a party in her honor where guests included her brother Jermaine Jackson and actresses Lindsay Lohan and Vivica A. Fox.
