Here's an interesting benefit concert lineup: Natasha Bedingfield , Sia and... Ozzy Osbourne ?

Those three artists, plus host Kathy Griffin , will all take the stage for An Evening with Women, a May 18th event that raises money for the L.A. Gay & Lesbian Center.  Proceeds will support the center's services and enrichment programs that help women and girls.

Ozzy didn't issue a statement about his participation in the event, but Kathy Griffin said, "I'm so honored to be hosting this year's An Evening with Women. It's a fantastic cause for the LGBT community and it's so rare Ozzy Osbourne and I get to have our lesbian time together, so that will be nice."

In a statement, Natasha added, "This event is going to be spectacular...My friend Sia is one of the best performers ever. I'm so excited for us all to get in the same room together surrounded by a crowd of wonderful and inspiring people.”

Sia, of course, is the voice you hear on the hits "Titanium" and "Wild Ones." The Australian singer-songwriter has also penned songs for Christina Aguilera , and helped mentor her team on The Voice .  She also co-wrote Rihanna's smash "Diamonds" and Ne-Yo 's "Let Me Love You (Until You Learn to Love Yourself)."
