US castings: Dexter, Grey’s Anatomy, How I Met Your Mother

Minor spoilers: Roma Maffia from Nip / Tuck and Boston Legal will appear in the fourth season of Dexter.

“I just did a role that could be a recurring character on Dexter,” she told EOnline.

“It’s Dexter plus one. I think it’s a surprising turn.”

A source added: “Roma’s role is a marriage counsellor/couples therapist who’s helping Dexter and Rita adjust to their new suburban family life.”

Meanwhile 24′s Kim Raver will join Grey’s Anatomy as a new surgeon and a possible love interest for Kevin McKidd’s character, Owen.

McKidd previously told media: “Someone comes to the hospital that he was connected to in his past, not his ex-fiancée, but it’s somebody we didn’t expect.

“I think it could get a little tricky, but exciting and interesting. Hopefully it will bring [Owen and Cristina] closer in the long run.”

And Project Runway‘s Tim Gunn has a guest role in the 100th ep of How I Met Your Mother.

In the episode, which will air in the fifth season, Gunn will act as a personal tailor/ fashion consultant as Barney (Neil Patrick Harris) tries to fix a major league ‘Suit Catastrophe.'”

Co-creator Craig Thomas says: “Tim is basically like Barney’s ER physician for a serious suit emergency.”
