Barefoot and dressed in a skimpy skirt and spangled navel-exposing top, Claudia Ciesla gyrates to the beat amid flashing strobe lights in a nightclub. The curvaceous, long-limbed dancer tosses back her black hair and grinds her hips as famous Bollywood actor Akshay Kumar sways towards her after he's done thrashing some thugs.

The promo video for the song “Balma” from the action-comedy “Khiladi 786” has been watched over four million times on YouTube and has made Ciesla, a German-Polish model, something of a sex symbol in India. Filmfare, a leading Indian film magazine, even dubbed the 24-year-old “the newest sizzler in B-town.”

Though the film has received mixed reviews, it's done well so far at the domestic box office. And the song “Balma,” which means “oh, beloved” in Hindi, has become a huge hit. The catchy number seems to be playing everywhere in Mumbai – in taxis, malls and at street food stalls.
