Jennifer Hudson's Grand Slam Performance

Jennifer Hudson's Grand Slam Performance

Using her talents for a good cause, Jennifer Hudson performed a dazzling set at the Wynn Resort in Las Vegas, Nevada on Saturday night (October 9).

Decked out in a gorgeous purple frock, the "American Idol" alum happened to be partaking in the Andre Agassi Foundation for Education's 15th Grand Slam for Children benefit concert.

Among the other stars lending a hand were Jason Mraz, Sir Elton John, Rob Thomas and AJ Green, who joined Miss Hudson onstage during her performance.

As for the cause, the Agassi event raises funds to help improve education for underprivileged youth in the Las Vegas community.

Voicing his thanks to Miss Hudson and everyone else who took part, Andre said in a statement, "We are honored that these international sensations are performing for this special 15th concert. The support received through the Foundation and from these renowned artists ultimately helps us make a difference in the lives of Agassi Prep students." (Hollywood Gossip)
