Farah and Kareena have worked together before, but the former feels their bonding became stronger while shooting for the song.
"Kareena's bonding with me became good after the song. She is also relaxed and is in a happier state after marriage. She is hardworking," Farah said at the launch of a new channel, Nick Juniors Tuesday.
Farah says both Kareena and Salman Khan were very supportive during the shoot.
"Kareena has put in a lot of effort. She rehearsed a lot for it. In fact, she let me do whatever I wanted for the costumes and look," said the choreographer.
"Salman was learning everything in one rehearsal. The shooting of the movie was over and the song was at the end, so everyone was relaxed. It was fun shooting in the end," Farah added.
After Kareena's song "Halkat jawaani" from "Heroine" became a hit, Farah wanted to give the actress a completely different look in "Fevicol se".
"Manish Malhotra and I were aware that she did 'Halkat jawaani' a few months before and we wanted to give her a different look. I wanted her to look a little mismatched and I also didn't give her too much make-up," she said.
Farah is happy that she has had an interesting 2012.
"(The year) 2012 was good. 'Shirin Farhad Ki Toh Nikal Padi' gave me good reviews and 'Fevicol se' has also became a hit. Ups and downs come in every year, but overall it was not bad," she said.
Farah's new film "Happy New Year" will go on floors next year and its leading lady is yet to be disclosed.
