British beauty Elizabeth Hurley admitted she wants another child but only after getting officially married to her Indian boyfriend Arun Nayar as being a single mother "sucks".

"Arun would love a baby and I'd love another one too. I don't know how much time there is for many but I'd secretly like twins," the 39-year-old Estee Lauder model was quoted by the Mirror as saying.

"I've been a single mother once. And I am sure every single mother in the world would agree with me - it sucks," added Hurley, who has been bringing up her 3-year-old son Damian alone since her boyfriend, billionaire Steve Bing, refused to admit he was the father.

"As I turn 40, I see marriage very differently. Now, although it's never been something I've thought important before, I can see why it is important for people to declare their intentions, make vows, and make proper, above-board plans for everybody, because that clarifies and simplifies things quite a lot."

The glamorous couple have been together for two years, but Hurley has to wait for Nayar to finalize his divorce with the first wife, Valentina Pedroni.

The Austin Powers and Bedazzled star has also revealed she intends to terminate her acting career to spend more time with her child.

"I don't want to leave my son for such long periods of time. A movie is three months and I've decided not to do that until he's older," she was quoted by The Sun as saying.

Hurley has recently appeared at a charity event in New York wearing a pink and green sari.

"Liz is known for flashing the flesh but by wearing the sari she is sending a message that she is extremely committed to Arun," said an onlooker.
