Former couple Ankit Gera and Roopal Tyagi are co-contestants on "Bigg Boss Nau", and the actor says though he shares 'cordial' professional terms with his former girlfriend, he is not sure how they will live under one roof.

"I have a normal relationship with Roopal Tyagi and have never spoken about what happened between us to anybody. We have worked together and share cordial relationship. But here ('Bigg Boss' house) we are staying together and we have never have done this, so let's see what happens," Ankit told IANS over phone from Lonavla before entering the 'Bigg Boss' house.

Ankit and Roopal starred in TV drama series "Sapne Suhane Ladakpan Ke" and started dating then. But the pair eventually broke up amid cheating rumours.

The actor feels break ups are a part of everybody's life, but "in celebrities life such things become controversies".

Ankit has entered the reality show, in which celebrities have to live in an isolated house for about three months sans any luxury. The ninth season, which is hosted by Bollywood's superstar Salman Khan, went on air on Sunday on Colors channel.

The actor, who also featured in "Mann Kee Awaaz Pratigya" and "Maharakshak Devi'", emphasised that he decided to do the show, famous for controversies and constant brickbats, in order to have a change in his life.

"Everybody wants a change in life and and I was tired of doing daily shows. So, I wanted to do reality show and I think 'Bigg Boss' is the best and the biggest reality show on Indian television," he said.

He added that his anger won't be an issue in the 'Bigg Boss' house as he knows how to control his temper.

"I don't get angry very fast. When someone says something to me I prefer being silent rather than retaliating," said the actor.
