Jessica is best known for her work as a journalist and as the author of the book Looking for the Big B: Bollywood, Bachchan and Me, which explored the phenomenon of Bollywood through the lens of Amitabh Bachchan’s stardom.

Over the years, she has written extensively about Indian cinema and culture, establishing herself as an observer of the industry. Jessica first came into the public eye in India during the late 1990s and early 2000s when reports of her alleged relationship with Aamir surfaced. The two reportedly met during the shooting of Ghulam (1998) and were said to have grown close. 

Rumours of their relationship, and later speculation about her having a child, circulated in gossip columns for years, though neither Jessica nor Aamir publicly addressed the matter in detail.
