Why is Manoj Tiwari`s marriage failing?

Mumbai: Bhojpuri star Manoj Tiwari`s 12-year-marriage is on the rocks - and apparently because of popular TV actress Shweta Tiwari. Manoj, a well-known singer and actor, was often seen breaking down at the mention of his family on ‘Bigg Boss 4’. But he finally opened up about the reason behind his troubled marriage. The actor said his wife, Rani, holds Shweta responsible for rifts between them and feels the two are romantically involved. Manoj also reveals that he has been living separately from his wife and daughter for the last six months. Shweta, who became a popular name after ‘Kasautii Zindagii Kay’, was left shocked with the news, and has decided to clear matters with Manoj`s wife after ‘Bigg Boss 4’. IANS
