Major Ugly Betty Casting News: Paula Abdul! Yaya Dacosta!

Holy Ugly Betty casting news!

The ABC series may be moving to Fridays in the fall, but it isn't going quietly.

First, it looks like Paula Abdul's first post-American Idol role will actually be to guest star on the show. Sources have confirmed to Michael Ausiello that the wakcy former judge will be playing a new temp at Mode. Look for her to bond with Amanda.

Which of these guest stars are you more excited about?

Meanwhile, America's Next Top Model cycle three runner-up, Yaya Dacosta, has also nabbed a key part.

The polarizing, part-time actress will take over the recurring role of Wilhelmina’s daughter Nico, a role originated by Jowharah Jones. Dacost will debut on the October 9 season premiere.

She's previously appeared on All My Children.

** UPDATE: ABC has now confirmed that Abdul will NOT appear on Ugly Betty after all.
