Over the past few weeks, numerous CSI favorites - Jorja Fox, George Eads and Marg Helgenberger most prominently - have renewed their contracts.

But we've got news on a new face coming on board the CBS drama: Sienna Guillory will portray a lab tech named Kacey Monohan.

“We have just started shooting and the atmosphere is electric,” the actress confirmed. “I suggest everyone holds on to their haircuts because my character is going to blow fans away, literally. She’s the team’s first full-time bomb tech and the action scenes will be explosive in every sense.”

Guillory added:

“I jumped at the chance to work alongside producer Jerry Bruckheimer, Laurence [Fishburne, Dr Ray Langston] and the rest of the cast. It’s a dream come true and the only thing that will top this is if they decide to mould a new spin-off show around me. They’d have to call that CSI: Kettering, though, so it might be a stretch.”

CSI returns with new episodes on September 23.
