It's not just actors and actresses who have controversial love lives. Playback singers in Bollywood too have often struck notes of disharmony in their married lives. We present top singers and composers who have hit the headlines as much for their scandals as they have for their music
The music director faced sexual harassment charges by popstar Alisha Chinoy (who mesmerized music lovers with her record breaking album Made in India). Roughly around 1996, Alisha accused Anu of having molested her. The Anu-Alisha spat took an ugly turn when Alisha demanded INR 2660000 (approx. Dhs153,400) as damages. But a defiant Anu vehemently denied the charges. Despite the drama, all Alisha got in return was a defamation suit worth INR 2 crore (approx. Dhs1,153,110) that Anu filed against her. Not surprisingly, Alisha swore to never to work with Anu again. But later, strangely she appeared to be in a mood for reconciliation and decided to put the past behind her. After years of acrimony, she recorded a song for him for Ken Ghosh's movie Ishq Vishq.
Sonu's Near Split
In 2005, the details of Sonu Nigam's troubled marriage came to light. Despite denials, it was known that Sonu was facing problems in his five-year marriage to Madhurima. The singer-turned-actor-turned-singer (again) has reportedly split with his wife, though both continue to live under the same roof. Infidelity was one of the main reasons touted for the discord was the proverbial third angle. The media linked Sonu with two women - singer Sunidhi Chauhan and the already-married Smita Thackeray who hailed from an influential political family. Reports stated that Smita was separated from her husband Jaidev Thackeray and around the same time, Sonu was trying to separate from Madhurima. In one of his interviews, Sonu told a website, "Madhurima and I need space, both of us are shattered, but life has to move on. I find there is no other alternative but to go our own ways. Madhurima continues to live in my house, but unfortunately, we do not communicate. I feel that it is better to part amicably, retaining respect for each other, instead of matters precipitating to a level where we do not even like to see each other's faces." Sunidhi and he denied dating but not many delved into the Smita Thackeray matter... probably because of the political angle. Years later, when Smita's son Rahul got married, one saw Sonu Nigam attending the marriage with wife Madhurima and their son. We don't know how their differences were eventually solved but a picture of Sonu Nigam displaying his affection for Madhurima by kissing him in public came as a surprise!
Sonu also had also lashed out against film journalist Subhash K Jha alleging sexual harassment and accusing him of "trashing" him in print.
Udit Narayan's Pati, Patni Aur Woh Act
Award winning singer Udit Narayan enjoyed a clean reputation until a scandal from the past hit him when his secret was exposed - that he allegedly had had married another woman! In true filmy fashion, a lady called Ranjana Jha created a flutter and forced her way into the posh Maurya Hotel on April 21, 2006 and claimed to be his wife. She was seen by the hotel staff squatting in front of the suite occupied by Udit, demanding restoration of her conjugal rights as his legally wedded wife. Udit accused Ranjana of lying and claimed that Deepa, his second wife, was the only woman in his life.What made matters worse was that the evidence (photographs, ration card and other legal documents) submitted by Ranjana before the Bihar's Women Commission, was substantiated and found authentic. On the basis of photographs and statements of the people who claimed to have attended their marriage in 1984, the Commission had prima facie found Jha's claim to be true.
After months of a bitter battle, charges and countercharges, finally Udit accepted that Ranjana was indeed his first wife. Much to the amusement of the media, Deepa and she denied having any differences between them and announced that they would live like sisters in true Indian tradition (bigamy be damned!). Ranjana withdrew her complaint. And Deepa was busy dismissing it as a "Ghar ka jhagda yeh to hota hi rahta hai."
Sukhwinder Singh's Disgusted Wife
Their relationship started when Sukhwinder was a nobody while his girlfriend Tejpal Kaur was a journalist in Punjab. Fighting her parents' wishes, the couple eloped and got married. But married life was different. It was alleged at Sukhwinder Singh got carried with the success of Chainyaa chainyaa song in Dil Se and started ill-treating Tejpal. The ultimate betrayal came in the form of the song Lucky Kabootar', which was written by Tejpal for a music company owned by a Canadian settled NRI Gurinder Singh. Sukhwinder apparently stole the song and gave it to Raaj Kanwar for his film Daag without crediting her. An angry Tejpal hit back. "Sukhwinder wants a servant not a wife but I am not that type. My husband is a disgusting man," she said.
It was also alleged that Sukhi would abuse his wife after getting drunk. Poor Tejpal then took a stand and told the media that she would not live with such a disgusting person and that she was capable of taking care of herself and her child.
Ankit Tiwari-

It is reported that Ankit has been charged for rape allegations while accompanying his brother Ankur Tiwari. He has been charged for raping a 28 year old girl. It is also heard that the victim had met Ankit through a common friend and the victim is in an alleged relationship with him.

Kumar Sanu:
A report was published in 1994 flimfare magazine that kumar sanu's wife rita filed a divorce suit . in her paper sanu's wife told that she wanted divorce and meenakshi seshadri was responsible for that. meenakshi and sanu both loved each other pasionately. similar report was published in other mag like aarpar etc .so media got a new hot topic. so they went to meenakshi and asked her about it. meenakshi angrily replied she did not know the reporter should ask kumar sanu and his wife. HOw mischevious behaviour of meenakshi, a woman seeked divorce from her husband blaming meenakshi.and meenakshi did not protest and remained silent . Anyone in world would protest and took legal action against sanu's wife. but meenakshi remained silent.. she knew if she would made any noise, then all trues were exposed and her chuimui and satisavitri image. Meenakshi then lived in a paradise ,anyone except herself knew what was her shady character.
When reporter asked rita sanu (sanu's wife).she blamed sanu and meenakshi for her on going divorce suit. She told reporter that she was pregnant but she had no money and sanu spent all his income to that wh**e. Rita told that at first she did not believe an educated and senior actress like meenakshi could do this kind of activity. but after watching some time all things came clear to me . She told also she had every information, how cruelty and vulgarly sanu was enjoying meenakshi, how dirtily meenakshi was satisfying sanu's sexual urge. Even they performed sexual acts in front of her when she protested against their shady relation.
Kumar Sanu also got married to two sisters(seperately). When he wanted to marry the third sisters apparently both his wives put their foot down and dragged him to court.
