Bollywood superstar Aamir Khan's wife Kiran Rao has suffered a miscarriage, the actor disclosed on his blog.

"I have bad news folks. Kiran and I lost our baby. Despite our best efforts we were unable to avert a miscarriage," the actor wrote in his blog.

"The last two months have been a struggle for us and that is one of the reasons I was absent from the blog in more ways than one. K (Kiran) and I need time to heal. I will be away for a while," Aamir wrote.

The news of Kiran's pregnancy became public in June this year when she was admitted to Breach Candy Hospital.

Aamir has two children -- son Junaid and daughter Era -- with former wife Reena. The couple divorced in 2002 after a marriage of over 15-years.

Khan married Kiran Rao in 2005. The actor met Rao during the shooting of 'Lagaan' in 2001. Rao was working as the assistant director to Ashutosh Gowariker.

Rao recently wrapped up the shooting of 'Dhobi Ghat', her first directorial venture, starring Prateik Babbar and Aamir Khan.
