Chinese actress Zhang Ziyi has strongly denied reports she earned $100 million by having sex with disgraced politician Bo Xilai — and astonishingly, sources close to the “Crouching Tiger, Hidden Dragon” star blame the reports on a smear campaign by a rival actress. It was reported that Zhang earned a fortune by prostituting herself to powerful Chinese men between 2007 and 2011, including to Xilai, who was recently removed from power following allegations he was involved in a murder plot. At the time, Zhang was dating financier Vivi Nevo. They were engaged in 2008, but split in 2010. Last night, reps for Zhang said she was consulting lawyers to sue for libel. Her rep said, “The accusations made against [Zhang] are completely false and defamatory. There is no truth in any of the allegations that have come forth, which are a result of calculated, cruel intentions against a well-respected, established actress. Legal repercussions are ensuing, and these slanderous reports will not be tolerated in any way.” Sources told us that Zhang believes the allegations were spread by a “jealous rival.” One said, “This isn’t the first time vicious rumors have been spread about her in the Chinese media by somebody who wants her roles and her success.” The source declined to name the rival, but added, “We will not put up with this, and will take every action necessary.”
