The 28-year-old Karwal has also participated in dating reality show 'Splitsvilla' and he says he is looking forward to add some excitement to the house.
"The concept of the show was new to me unlike the other reality shows that I have doen before. Not much is really happening in the house right now, other than screaming and shouting. I have participated in 'Splitsvilla' so I will bring that experience to play here," Vishal told PTI.
Model-actor Mink Brar recently entered the show as a wild card contestant.
When asked if there would be sparks flying after his entry, he said, "I cannot reveal anything right now. I do not have a strategy in mind. I have seen the episodes and I know a few people like Sapna (Bhavnani), Mink (Brar), Sana (Khan)."
Vishal has also played the lead in daily soaps - 'Bhagyavidhaata', 'Rishton Se Badi Pratha' and most recently he played Lord Krishna in 'Dwarkadheesh Bhagwaan Shree Krishna'.
When asked about the other men in the house, Vishal said, "I am really going to miss Siddhuji because he will leave the house when I will get in. I wanted to sit with him. Vrajesh Hirjee is a very cool person and a funnyman but somehow he has become very serious in the house.
