Kelly Osbourne is taking on a killer new role in this week's all-new episode of CSI: Cyber!

Described as the "most diabolical villain" that the CBS drama has ever had, Osbourne's character is a hired hitman who can delete all digital traits of a person's existence -- and only ET has the exclusive first look.

"I play Stella, who is an Internet assassin," Osbourne dishes in our sneak peek video above. "It's really been fun and educational because I am not technologically savvy -- at all."

"She's the angel of digital death," the former Fashion Police host continues. "The method to Stella's madness is that she kills people digitally. She doesn’t actually physically murder anybody."

Stella can clear bank accounts, void social security and even file a death certificate in your name -- thus essentially eliminating someone from existent without any actual bloodshed.

The purple-haired 31-year-old reveals that she jumped at the chance to be a part of this series. "I'm an avid fan of anything CSI," Osbourne gushes. "And sometimes when you watch the episodes you can see where it's going, but in this episode, you really don’t know where it's going."

CSI: Cyber airs Sundays at 10 p.m. ET/PT on CBS.
