Ive been in contact with Courtney Kemp, who is a good friend of mine.

Courtney and I have been trying to figure out a way to work together for some time.

We figured hell or high water, were going to find a way to sneak me in.

Its a monster show and I thought it would be fun to pop in for the final season.

Its an interesting character.

Hes just been off-screen this whole time.

Its kind of cool to come in with a character thats kind of been ever-present.

Did anyone notice you on set?

Or was it an open secret that Jesse was there?We kept it pretty secretive.

I just did my scenes with Joseph and kind of snuck in and snuck out.

I think Omari Hardwick knew.

I dont remember you having all those tattoos.Thatd be a hell of a reveal!

I had a fun time with their great makeup department playing around with some prison tats.

This is the first time Ive been full-body tatted since I did theRihanna video Russian Rouletteages ago.

I had full body tat for that.

It was fun to do and it might be something I do in real life.

Who the hell knows?

Im open to doing cool, creative, different work that I havent done before.

Its certainly a possibility as far as I can tell.

Did you have to ask for time away fromGreys to do this?They were very accommodating.

This is my 11th year.

Everybodys really lovely and does their best to make it work.

Im onGreys, Ive got a relationship with a character on another Shonda show.

Im doingLittle Fires Everywhereon Hulu.

Ive done a couple of movies.

Im getting ready for a play.

I cant say enough about how accommodating and loving they are.

Well, I hope you got to keep that gold chain you wore in the episode.I mightve swiped it.

Well keep that between you and me.
