Kushal Tandon proposed to Gauhar Khan in the Bigg Boss Saath-7 house and this boosted viewers' curiosity, while Tanisha Mukherjee-Armaan Kohli's camaraderie is keeping the audiences hooked to the ongoing season of the reality show.
How real are these relationships? Ex-contestants claim inmates sometimes "fake romances" for survival and to boost viewership ratings and sometimes "they attach themselves to someone" due to loneliness in the house, where they are locked up for three months without contact with the outside world.
Sambhavna Seth, who was seen in the second season of "Bigg Boss", said: "The people, who come in 'Bigg Boss', have it in their mind that if they are attached to someone and give a romantic angle to the show, it will increase the TRPs (television rating points) and also that it will help them last longer in the show."
"The second thing is that sometimes one can feel so lonely inside and because of that they attach themselves to someone," the actress told.
Another ex-contestant, model Pooja Misra, told that to a great degree, people feel "lonely" as they are away from their families and are surrounded by people who are not their friends.
Added Pooja: "Fake romances happen because they want to play the game of TRP with somebody whom they are romancing apparently, but actually they are just looking for a friend who is just sticking with them as they don't have a real friend in the 'Bigg Boss' house.
"So, yes, on reality TV people fake romances and once they step outside the house they don't keep in touch, they don't talk."
The "Bigg Boss" house has seen it all - from cuddling to hugging and kissing to lover's tiffs during each season. Alas, hardly any relationship survived outside the house.
The failed romances are a testimony to the fact that relationships in "Bigg Boss" house come with an expiry date.
If actors Aryan Vaid and Anupama Verma's romance set the ratings soaring in the first season, the duo went separate ways after the show.
The same was the case with Pakistani actress Veena Malik and Bollywood actor Ashmit Patel. They scorched the small screen in season four, but their romance was nowhere to be seen once the show ended.
In the same season, TV actress Sara Khan had a 'nikaah' with her longtime boyfriend Ali Merchant. Their marriage was called off immediately after the two got evicted from the show.
Other popular couples whose chemistry spiced up the show are Pooja Bedi-Akashdeep Saigal, Monica Bedi-Rahul Mahajan, Claudia Ciesla-Parvesh Rana, and Vishal Karwal-Sana Khan.
Once evicted, they all came back to the "we are just friends" tag, except Pooja and Akashdeep as their relationship is still going strong.
TV actor Rajev Paul says it's very "normal" to get close to someone, and it depends on an individual how he or she wants to take it forward.
"I grew fond of Sana Khan and even she was fond of me, but we were not involved romantically at all. In this season, Armaan and Tanisha are from the film background, so they share the same opinion, likes and dislikes, and thus are seen spending time with each other," added Rajev, who came in season six with ex-wife Delnaaz Irani.
"It's true that it's difficult to figure out what is fake and what is real, but it's practically impossible to fake it for 100 days in front of so many cameras. All those people who really fake it are good actors. I don't know whether it continues outside for others or not, but me and Sana are still friends and will always be friends," the actor told.
In the current season, as a special treat, Bigg Boss even arranged a date for Gauhar and Kushal so that they could have a good time. There were candles, slow music, balloons and roses - a set-up similar to what Vishal and Sana got.
With as many as 84 cameras spying on them, the inmates have not been able to hide their love.
According to Shradha Sharma, who featured in "Bigg Boss 5", not a single corner in the house is left without a camera, so after spending some days, people get "used to it and behave according to their originality".
Whatsoever the reason, romance in the house definitely acts as a visual treat for the viewers!
