The actress will be seen as Amit's US returned friend and her entry will create trouble for Amita.
"She is basically from the US. Amit is a friends' friend. There will be a misunderstanding between Amita and Amit because of me," Leena told IANS.
"I liked the role and the way they narrated the story to me. This is why I took it...I started shooting a few days back," she said.
Leena has been a part of Gujarati cinema prior to Hindi television.
"For Gujarati cinema, I didn't give any audition. Someone saw my pictures and offered me the film. On the launch of the first film, I was offered the second one. I did three to four films and then came to Mumbai. I did one Gujarai serial and then did 'Bandini'," she said about her acting journey.
So far, she has done TV shows "Tujh Sang Preet Lagai Sajna", "Ganga Kii Dheej", "Ek Nayi Chhoti Si Zindagi" among others and says all of them are important to her.
"All my shows gave me a different image and publicity. I can't say one has given me more than the other," she said.
The actress was also seen in Sajid Khan's "Himmatwala".
"In 'Himmatwala', I almost played the parallel lead. I liked it and people loved me. I got good feedback. In future, I want to play main heroine and a bubbly or tapori kind of role etc," she said.
