Actress Jacqueline Fernandez is going through a great phase, working with big stars under big banners, and her first hero, Riteish Deshmukh has a great opinion of her, terming her a "live wire" on the sets of their latest film "Bangistan".Asked at a media interaction about the equation he shared with Jacqueline, Riteish said: "One thing that has not changed about her is her intention to work harder every time. She is extremely hardworking. Whenever she comes on the sets, she is like a live wire, there39s a certain amount of energy she has that she brings on the sets or wherever she is."What has changed is the fact is that she39s become a better performer, even more confident dancer, you can see that in her performance in songs, there is a certain level of perfection that she39s attained. Hats off to her and I wish her all the best. I39m really happy for her that she39s doing so well."Jacqueline39s first two films were with Riteish - "Aladin" and "Jaane Kaha Se Aayi Hai". But she got more recognition for her song in "Housefull" which Riteish was also a part of. They worked again in "Housefull 2" and then she went on to do many successful films like "Murder 2", "Race 2" and "Kick"."Bangistan" also stars Pulkit Samrat and is produced by Excel Entertainment.
