British singer Kevin Simm is a second time father. The star, who recently reunited with pop act Liberty X, welcomed a son, Oliver, late last month (Nov13). Explaining his tiredness on U.K. morning show Lorraine, the star says, "(We welcomed) my second, a boy, Oliver. He's about two and half weeks old. "It's going great, obviously I miss him while we are on tour. But you're always tired in a band so it makes no difference." Simm has another son, Charlie, with his wife, Laura. Liberty X was one of the defunct pop groups which reformed as part of U.K. TV series The Big Reunion earlier this year (13).
