Cher's son ELIJAH BLUE ALLMAN has slammed his mother's former lover Tom Cruise, insisting he should stop talking about his personal life because "people aren't buying into his whole act". The BELIEVE singer dated Cruise in the 1980s, before he made Top Gun and, according to her son, the pair even lived together. Allman, who is Cher's son with musician GREGG ALLMAN, claims Cruise has changed significantly over the years. He tells American publication Us Weekly, "He was totally different. We lived with him for a couple of years. "(Now) he shouldn't be trying to help his career by talking about his personal life. People aren't buying into his whole act." Allman made headlines last week (ends27AUG06) when he appeared on the raunchy Howard Stern radio show and revealed that after he had sex with Paris Hilton he scrubbed down his private parts with bathroom cleaner Tilex because he feared he had contracted a sexually transmitted disease from the aspiring singer.
