Bipasha Basu and Karan Singh Grover`s sizzling chemistry in 'Alone' has set the temperatures soaring and Bipasha too agrees that they make a great on-screen couple.

When asked how was it working with Karan, who is marking his Bollywood debut with the movie, the Bong bombshell said, "Karan is a fantastic actor, that`s the first necessity for me. When the casting process was on, they told me that they are casting him and he has done a body of work in television and he is very very popular and it was very important that the two lead characters of the movie- Kabir and Sanjana looked very good together, they had to look like a couple and we have a great chemistry on screen. He is very easy to work with so yes, I had a great time working with him."
