Tony. McGee. Playboy centerfolds. These things don't often mix on NCIS, but that's about to change come March 16, when Shanna Moakler guest stars on the hit series.

The former Miss USA will be playing the girlfriend of a Navy diver who dies under mysterious circumstances. Shanna is also known for a stint on Dancing with the Stars.

That and being married to (and separated from, and back together with, and divorced from, and fighting via MySpace with) Travis Barker of Blink-182 fame. She's cute.

In somewhat more important NCIS guest starring news, Rena Sofer will definitely appear in multiple episodes beyond March 2 as no-nonsense lawyer M. Allison Hart.

What do you think she and Gibbs have going on?

Former Playboy model, Miss USA and Dancing with the Stars contestant Shanna Moakler is coming to NCIS. That's not a piece of casting news we saw coming, but we're intrigued!
