sister c x factor 'The X Factor' Top 24 revealed: Did your favorites make the cut?“The X Factor” finally revealed which 24 acts are semi-finalists and therefore get to travel to the judges’ homes to be mentored — and whittled down even further. Check out the full Top 24 here in our gallery.

The Young Adults, or 18-24 year-olds, are Cece Frey, Willie Jones, Jennel Garcia, Nick Youngerman, Paige Thomas, Jillian Jensen and are being mentored by Demi Lovato, with special guest mentor Nick Jonas.

The Groups are Sister C, Dope Crisis, Emblem3 and then three created groups that are calling themselves Playback, LYLAS and One4Five + Lyric DeQueen. Their mentor is Simon Cowell and guest mentor Marc Anthony.

The teens, 13-17 year-olds, are Beatrice Miller, James Tanner, Carly Rose Sonenclar, Diamond White, Reed Deming and Arin Ray and are mentored by Britney Spears and guest mentor Will.I.Am.

The 25 and over group is Jason Brock, Daryl Black, David Correy, Tara Simon, Tate Stevens and Vino Alan, being mentored by L.A. Reid (who is not happy about it) and guest mentor Justin Bieber, which is an interesting call for the 25+ group.
