Actress-comedian Rachael Harris (Fat Actress, In the Motherhood) is relocating to Cougar Town to play the potentially recurring role of Shanna, Courteney Cox’s judgmental nemesis, sources confirm to me exclusively.

Wait, there’s more!

Ferris Bueller’s BFF, Alan Ruck — who’s currently recurring on FlashForward — has been cast as her husband, Frank. Look for Frank to develop a bit of a crush on Cox’s character, further inflaming the Jules-Shanna rivalry.

In case you didn’t hear, the Bill Lawrence-produced Cougar Town was just handed a full-season pick-up from ABC.

Courteney Coxhas admitted that the character she plays on new show, Cougar Town is her favourite yet.

The former Friends star plays recently divorced ‘cougar’ Jules Cobb on the show. She told Mercury News that she likes “playing this character more than any character I’ve ever played.”

She stated: “I don’t think I’ve ever starred in something where I really am in every scene. I hope this show is a huge hit and that people love it.“Because I like playing this character more than any character I’ve ever played. This show says what I think.”

ABC on Thursday handed full-season pickups to three of its four new fall comedies, the single-camera half-hours “Modern Family,” “Cougar Town” and “The Middle.”

“Modern Family,” one of the best received new series, and the Courteney Cox starrer “Cougar Town” have been early ratings standouts.

While they dipped in their third airing this week, the two shows continue to be solid anchors of ABC’s all-new two-hour Wednesday comedy block in the 9-10 p.m. hour.

“The Middle,” which stars Patricia Heaton, has been less impressive at 8:30 p.m., but has built on its “Hank” lead-in in both airings so far.

As for “Hank,” the fourth piece of ABC’s comedy block, there is no word on its future.

“Hank,” starring veteran Kelsey Grammer, is the only multi-camera comedy among the foursome and has fared much worse than the others in critical response and in the ratings.

ABC is yet to make a decision on the fifth new Wednesday series, low-performing dramedy “Eastwic

ABC’s new sitcoms Modern Family and Cougar Town slipped in their second outings, but they were still the highest-rated shows of the evening last night.

Modern averaged a 3.7 adults 18-49 rating at 9 p.m., according to Nielsen overnights, the night’s top-rated show and off 12 percent from last week’s 4.3 for its debut.

At 9:30, lead-out Cougar Town averaged a 3.6, dropping a bit more, 18 percent, but still tying with CBS’ Criminal Minds, its timeslot companion, for the No. 2 program of the evening.

The combination of Modern and Cougar finished just ahead of Minds in the timeslot with a 3.7, with some of last week’s viewers possibly drifting back to Fox’s Glee. The comedy saw its ratings rise week to week for the first time in its brief four-week run, up 7 percent to a 3.2, equaling its average the week before ABC premiered its comedies.
