British starlet Sofia Hayat, who celebrated her birthday in a two-piece last year, ushered in her birthday recently in yet another bikini.

Only this time, it was for a cause.

She was supporting the People for the Ethical Treatment of Animals (PETA) appeal to not use animals to test cosmetic products.

Held at the Grand Sarovar Premier hotel in Goregaon, a western Mumbai suburb, the birthday party went on till the wee hours of morning.

The birthday girl also mentioned being keen on doing an item number in a Salman Khan movie.
