OKAY,
After not much research on my part, I ran across this info:
The spoiler blog is reporting the following people as Top 24 contestants based on multiple sources that have said so:
Gals: Ayla Brown, Becky O'Donohue, Brenna Gethers, Heather Cox, Katharine McPhee, Kellie Pickler, Kinnik, Lisa Tucker, Mandisa Hundley, Paris Bennett.
Guys: Ace Young, Bobby Bennett, Bucky Covington, Chris Daughtry, David Radford, Elliott Yamin (also known as Efraym Yamin on some lists, but it's the same guy), Gedeon McKinney, Kevin Covais, Patrick Hall, Sway, Taylor Hicks, William Makar.
Which, if my math is correct, leaves us 2 females short of a full 24 spoiler list.
Any guesses?
