Bollywood celebrities including megastar Amitabh Bachchan, filmmaker Karan Johar and Simi Garewal have wished the "super" filmmaker Farah Khan on her 51st birthday on Saturday.

Her husband Shirish Kunder, brother Sajid Khan and friend and designer Manish Malhotra have wished her a year full of happiness, luck and laughter. 

Farah is a film director, producer, actress and choreographer. She is best known for her choreographic work in numerous Hindi films. 

The 51-year-old has choreographed dance routines for more than a hundred songs in over 80 Hindi films. 

She has worked on international projects such as "Marigold: An Adventure in India", "Monsoon Wedding" and the Chinese film "Perhaps Love".

She turned director in the 2004 film "Main Hoon Na", which starred superstar Shah Rukh Khan, who she has been good friends with.

In 2012, Farah made her film acting debut in a leading role in "Shirin Farhad Ki Toh Nikal Padi", directed by Bela Bhansali Sehgal.

Farah trained Colombian singer Shakira for a Bollywood version of her song "Hips Don't Lie" for the MTV Video Music Awards in 2006 and has also choreographed Kylie Minogue for the song "Chiggy Wiggy" in the 2009 movie "Blue".
