SIR Mick Jagger's former wife Jerry Hall has warned women not to be tempted by rock star charms - insisting U2 frontman Bono is the only exception. The Texan model/actress, who was also once engaged to singer Bryan Ferry, hopes her tempestuous love life will put impressionable girls off rockers for good. She tells German magazine Gala, "So many women fall for rock stars but, ladies, believe me, life with such a man is not easy. "Bono's the only man who has made it work." The Irish singer has been married to childhood sweetheart ALISON STEWART for 23 years.
