Jennifer Hudson Looks AMAZING in Purple…

Singer Jennifer Hudson performed onstage during the Andre Agassi Foundation for Education’s 15th Annual Grand Slam for Children benefit concert.

The event was held in Agassi’s hometown of Las Vegas at the Wynn Hotel and J-Hud looked amazing in purple as she performed her hit DREAMGIRL’S song “And I Am Telling You I’m Not Going.”

Doesn’t Jennifer, who is an official spokesperson for weight watchers, look amazing in her new size 6 frame?

Jen was joined by Elton John and Jason Mraz. The three musicians, along with a host of other celebrity guests, helped raise a total of $8.5 million for Agassi’s Foundation for Education. Agassi was pleased by the response and told the Las Vegas Review Journal:

“Tonight is an example of what Vegas is. It’s about standing shoulder to shoulder, together, and really solving issues that affect all of us.”

The Agassi Foundation raises funds to help improve education for underserved youth in the Las Vegas community.
