 Bollywood superstar Aamir Khan announced Saturday that he is splitting with his wife of 15 years, filmmaker Kiran Rao.

The A-list couple released a statement saying their break-up had been agreed but they would raise their son together and still work on joint projects.

"In these 15 beautiful years together we have shared a lifetime of experiences, joy and laughter, and our relationship has only grown in trust, respect and love," they said.

"Now we would like to begin a new chapter in our lives - no longer as husband and wife, but as co-parents and family for each other."

Khan and Rao met while shooting a film in 2001 on which Rao was the assistant director, and they married in December 2005. 

The 56-year-old actor, whose film about wrestling, Dangal, made him the top Indian star in China, was divorced from actor Reena Dutta in 2002.

"We began a planned separation some time ago, and now feel comfortable to formalize this arrangement, of living separately yet sharing our lives the way an extended family does," Khan and Rao said.

"We remain devoted parents to our son Azad, who we will nurture and raise together. We will also continue to work as collaborators on films, Paani Foundation, and other projects that we feel passionate about," they said.

Khan and Rao, 47, thanked their family and friends "without whom we would not have been so secure in taking this leap."

"We request our well wishers for good wishes and blessings, and hope that - like us - you will see this divorce not as an end, but as the start of a new journey."
