The chemistry between Upma -- a blend between actors Upen Patel and Karishma Tanna -- is working well for the ratings of "Bigg Boss Halla Bol", says host Farah Khan.

The closeness between the two contestants of the reality show has become a major talking point of the ongoing extension of the "Bigg Boss 8" season.

"Upma (Upen and Karishma) is doing very well. I'm happy that TRPs are doing very well. I cannot take the credit for that. I think the show has also become more interesting now," said Farah, a popular choreographer-filmmaker.


"I'm happy that the show's TRPs are steady because if the TRPs fall, then definitely the blame would be put on me," added Farah, who was present at the music launch of film "Mrs. Scooter" here Monday.

"Bigg Boss Halla Bol" series started with five challengers from past seasons of the show, competing with five "champions" from the eighth "Bigg Boss" seasons. It airs on channel Colors.
