Cruise-Cruz just couldn't make their 2001 to 2004 romance last. A September 2012 Vanity Fair article reported that the Vanilla Sky costars split because she wouldn't convert to Scientology, refusing to give up her own devout Buddhist beliefs. But in two different statements by the stars' reps, they denied that their religious differences were to blame. "They broke up at the end of January and it's amicable," said Cruise's publicist. Added Cruz's spokesman: "They remain good friends."
