"When I was two years old, my dad got me a bikini from Australia. I have that picture and that looks really cute. So, from that time I have been a girl who loves sun and beach," the 34-year-old said here Monday after she was declared the brand ambassador of India Resort Wear Fashion Week.
"So, it's something which comes naturally to me. It's not definitely to create a screen image, I am very comfortable off-screen also. I am totally a beach bum," she added.
Bipasha has donned the two-piece in films like "Dhoom 2" and "Players".
Asked which Bollywood actress she feels looks confident in bikinis, she said: "I think Zeenat Aman, at some point, was the hottest actress ever.
"She is iconic, and to match her sexiness is tough for all of us contemporaries.
"In today's time, all girls are fit and look hot and glamorous. I think anyone can look good in a bikini.
"It's just the factors - you need to be little confident. It is not about wearing a bikini, it's about wearing your confidence more," she added.
