Washington, Nov 23 Shakira has admitted that she's desperate to start a family with her fiancee Antonio de la Rua.

The 32-year-old singer, who has been engaged to Antonio de la Rua, 36, for the last four years, said that she's planning to try for a baby as soon as possible because her 'biological clock is ticking'.

"I'm dying to have a baby. We both are. I'd like two and Antonio would like three," Contactmusic quoted her as saying.

"So probably after my next album, which comes out next year. I don't think it could be sooner because in 2010 I'll be touring as well.

"In fact, my biological clock is already ticking and I don't know how to describe it. It's just becoming a physical need now," she added. (ANI)
