"Bigg Boss 9" contestant Keith Sequeira is having a tough time on the show -- with his girlfriend Rochelle Rao on one side and partner Mandana Karimi on the other.

However, rumours have been doing the rounds that the show-makers plan to raise the drama quotient and create further troubles for Keith by introducing his ex-wife and actress Samyukta Singh on the show.

"The makers feel Samyukta's presence will heighten the tension in the 'Bigg Boss 9' house. However, she is yet to decide if she should take on the offer. In case she does, it will come as a shock to Keith and Rochelle," a source told Mid-Day.

According to reports, Keith and Samyukta were married for around seven years before they parted ways. The duo had been dating before Keith established himself as a VJ.

Samyukta played the lead in 1994 release "Salaami" opposite Ayub Khan. Although the film bombed at the box office, Samyukta is best remembered for the film's song "Chehra Kya Dekhte Ho", which was a chartbuster.

Recently, she was in news for leading a campaign against the killing of stray dogs in Kerala. Samyukta is TV actress Natasha Singh's sister, who was part of popular series "Dekh Bhai Dekh". 

If Samyukta agrees to be a part of the show, it would surely increase the tension inside the mad house and entertain viewers with juicy gossips.

Additonally, if Keith mends his differences with ex-wife during her stay in the house, will it affect his girlfriend Rochelle, who is already insecure with Keith's closeness with partner Mandana? Only time will tell.
