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

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

However, the actress ducked questions about her marriage. "I said the clock is ticking... I never said anything about marriage," she said.

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

Sen adopted Renee in 2000 and Alisah in January this year.
