Kelly Osbourne - Kelly Osbourne Stars In Drop Dead Diva

The E!'s Fashion Police commentator joined the cast of the Lifetime network's legal series on Thursday (05Jul12) to shoot her episode for the current fourth season.

Actress Kate Levering posted a photo of Osbourne on her Twitter.com page, alongside the caption: "Star studded courtroom on our last day of @DropDeadDiva S4 (season four)!"

Osbourne also shared an image of her in action on the witness stand, writing, "Here is a pic (sic) of me during my dramatic courtroom scene!"

Osbourne, whose episode is expected to air later this year (12), is not the first celebrity to star in Drop Dead Diva - Kim Kardashian and singer Paula Abdul have also previously appeared on the show.
