After adopting two children, former Miss Universe and actor Sushmita Sen now wants to give birth to a child.

"I will go for biological baby because the clock is ticking for me," Sushmita, 34, told reporters Thursday on the sidelines of a preparatory workshop for the 2010 Miss Universe pageant.

Sushmita's production company Tantra Entertainment was awarded the India franchise to select participants by the Miss Universe Organisation.

The Hyderabad-born actress ducked questions about her marriage.

"I said the clock is ticking... I never said anything about marriage," she snapped when reporters asked whether marriage was on the cards.

"Every girl wants her prince charming. I have stopped thinking about it long back but still I want it," said the actress.

Sushmita adopted daughter Renee in 2000 and another girl Alisah in January.
