Makers of upcoming movie "Ae Dil Hai Mushkil" starring Ranbir Kapoor, Anushka Sharma and Aishwarya Rai Bachchan have started shooting the film in London.

It is Karan Johar's first directorial venture after a gap of three years, since his last movie "Student of the Year" (2012).

Aishwarya Rai Bachchan, who will soon be seen in her comeback movie "Jazbaa", has teamed up with Ranbir and Anushka for the first time for "Ae Dil Hai Mushkil", which is being touted as a complicated love story.

Director Karan Johar recently shared a picture from the sets of the film in which Ranbir Kapoor and Anushka Sharma are seen posing with a clapper board as KJo tweets, "You can never meet with the demands of the heart....our journey begins today...#AeDilHaiMushkil (sic)"

Meanwhile, Anushka Sharma also informed how excited she is to begin shooting for "Ae Dil Hai Mushkil" on Twitter and also sought good luck wishes from her fans.

Ranbir and Anushka will be sharing the screen space together for the second time, their first film being "Bombay Velvet" which also featured Karan Johar.

While fans are familiar with Ranbir and Anushka's chemistry, Ranbir and Aishwarya Rai coming together for the first time has been garnering a lot of curiosity.

Produced by Dharma Productions, "Ae Dil Hai Mushkil" will reportedly feature Sunny Leone as well, in a cameo role.
