The "Kya Kool Hain Hum 3" trailer has crossed a whopping 10 million hits on YouTube, and the makers should have only one person to thank — Mandana Karimi.

Looking supremely hot in a two-piece swimsuit, the actress has shown off her curves and mouthed some very double-meaning dialogues. But, all this didn't come easy to the Iranian beauty. In a behind-the-scenes video released by the "KKHH3" team, it was revealed that she had to pose in short, skimpy clothes all day long. The making-of clip has already gone viral, and her fans are going nuts over how awesome she looks in it.

Confident and thrilled about the shoot, the actress looked jaded but happy by the end of it. However, this faith in herself has seen a sharp dip in recent times, courtesy "Bigg Boss 9". Often criticised for her actions and words, Mandana has been coming across as really tired and disappointed in the people she's currently surrounded by.

In other news, a strong buzz suggests she is being considered for the female lead in Salman Khan's "Sultan". The superstar batting for her has triggered news that the makers of the upcoming action-drama are looking to rope her in.

Scheduled for a 22 January release, "KKHH3" also features Aftab Shivdasani and Tusshar Kapoor, who play porn stars in it.
