Former British pop singer TINA BARRET has ruled out following the Spice Girls' example and staging a reunion with her defunct group S Club 7. The Reach For The Stars hitmakers split in 2003 after five years together, but Barret fears continued strained tensions would make a comeback tour almost impossible. The 30-year-old says, "We haven't spoken since we split. By the end, we were fighting all the time."
