Mumbai, Jan 20 (IANS): The closeness of "Bigg Boss 8" contestants Karishma Tanna and Upen Patel has become one of the talking points of this season of the show. Karishma says they like each other but it is too early to tag them as a 'couple'.

On Pritam Singh’s birthday, RJ Malishka from RED FM along with Pritam’s wife and two fans called up at the “Bigg Boss Halla Bol” house to wish him.

It was then that Malishka asked Karishma and Upen some questions from their fans. The first question was whether Karishma and Upen are a couple?

Karishma instantly said: "No comments",”but later she went on to add that it is too early for them to call themselves a couple. However, she didn't deny that they like each other.

Upen entered the house as a guest after Ajaz Khan, one of the challengers, was asked to exit the show. There are rumours that the duo got intimate inside the house last week.

When Malishka inquired about her earlier claims of having a relationship outside the house, Karishma said what she had outside the house did not feel complete.

And since the time Upen has come into the house again, she feels more positive and he makes her happy.

The extended version of "Bigg Boss 8" in the form of "Bigg Boss Halla Bol" series is hosted by filmmaker Farah Khan.

The episode featuring Karishma opening up about Upen will be aired Tuesday on Colors channel.
