In what has already been a busy week for pilot pickups, ABC, Fox and NBC have each added an additional series to their lineups next season, according to the Live Feed.

First up in 'Perfect Couples' from NBC, a new romantic comedy starring Olivia Munn, Kyle Howard and Christine Woods. The show, as you might guess, follows three couples who struggle to define the perfect relationship.

Meanwhile, good news for 'Arrested Development' fans: Earlier this evening, FOX gave the thumbs up to 'Running Wilde,' the latest comedy from Mitch Hurwitz. The show stars another 'Arrested' alum -- Will Arnett -- as "Beverly Hills jerk" who falls for a charitable woman ('Felicity''s Keri Russell) who clashes with his values.

Dolly Parton will reportedly return for the final season of 'Hannah Montana,' reprising her role as Aunt Dolly. Parton -- who previously appeared in two episodes of the hit Disney Channel series -- revealed the big news on Friday, although she did not specify when the episode will air. Recently, it was revealed that 'Hannah Montana' would end after its fourth season. [Knoxville News Sentinel]

More casting news after the jump.

If you've been keeping track of all of the casting and pilot news that's been happening the past several weeks, you know that there are approximately 91,000 new pilots being filmed. About six of them will actually make it to the air. Here's the latest:

Christine Woods of 'FlashForward' has landed a role in NBC's 'Perfect Couples.' a comedy about three different married couples. 'FlashForward' fans shouldn't panic over this casting though. Woods would stay with that show if it gets a second season. Besides, there are many other reasons to panic about FlashForward.

In other news, 'ER's' Goran Visnjic and Katee Sackhoff will star in ABC's 'Boston's Finest,' about an ex-cop and a detective trying to figure out some mysterious conspiracy that has hurt them both. Yup, another show will a conspiracy angle, and yet another show with a good-looking man and woman team up to fight evil (see also 'The X-Files,' 'Fringe' and several other shows).
