A two-year-old rumour that Aamir has always denied came to dog the divorced 40-year-old actor as the Aaj Tak news channel splashed photographs of Hines and her two-year-old son Jaan.
Jaan Harry Hines was reportedly born in London Sep 14, 2003, when the reported fling was long over.
Hines was quoted as saying by the channel that she had resisted pressure from Aamir to abort the child, and had assured him she would raise Jaan on her own.
She was further quoted as accusing Aamir of not inquiring about the child even once. Hines is reported to be working on a biography of Amitabh Bachchan.
The detail-loving actor recently divorced from his wife of 15 years, Reena, and is currently in a relationship with Kiran Rao.
His portrayal of Mangal Pandey, the revolutionary said to have sparked the 1857 revolt against British rule, has been much talked about in recent times.
