Stars to show off voices

? Joe Pantoliano, Morgan Fairchild, Kim Alexis and Carmine Gotti are among the celebrities who will compete in the new VH1 series “But Can They Sing?”

The six-week competition will premiere Oct. 30. The winner will receive a cash donation to his or her favorite charity.

Each week, contestants will undergo training with two vocal coaches and a movement-dance instructor to prepare for their performance in front of a live studio audience.

Viewers will cast their votes online, by text messaging or by a toll-free number to decide who stays and who goes home.

The other competitors are Antonio Sabato Jr., Larry Holmes, Bai Ling, Michael Copon and Myrka Dellanos.
