As soon as she announced her plans to join Twitter, videos of her posing topless in an old advertisement surfaced on the site YouTube.
The ad, which also features Vivek Oberoi, was reportedly shot in India 11 years ago when Bipasha was bound in a contract with the New York-based Ford modelling agency.
It was a television commercial for the New York Lotto but was shot in India. The ad is directed by Ken Nahoum. The video is posted online by Tommy Kane, who was the art illustrator for this ad.
A Mumbai tabloid quoted Bipasha's manager saying: "Bipasha had done this ad in 1999 when she was modelling for Ford Modelling Agency in New York. It was done as an international assignment and was meant for the international market. I don't know why such an old ad has surfaced now.
However, Vivek's spokesperson refused to speak on the commercial, saying that they have no idea of the ad.
