Model-actor Upen Patel says his relationship with reality TV star girlfriend Karishma Tanna is going strong.

Upen, 32, proposed to the 31-year-old "Grand Masti" star during their outing on the last season of the popular TV show "Bigg Boss".

"We are very much together till now. Things are going extremely good at our end since we met each other. We are in a very happy phase personally and professionally," he told PTI.

Upen and Karishma, who will be next seen opposite Sunny Leone in the upcoming film "Tina and Lolo", are going to be a part of dance reality show "Nach Baliye".

When asked about it, Upen said, "Yes, we have been offered the show but we are still in the process of negotiations. I love dancing and on the show people will see a different side of me. As far as my experience goes, I feel reality shows are very good platform to connect with your audience because you meet them through the TV which is being watched by so many."
