Courteney Cox-Arquette is getting ready to have another child because "time's a-ticking".

The 45-year-old actress has revealed she and husband David Arquette - who presently have daughter Coco, five - are preparing to have a second child while they still can.

Courteney is quoted by gossip blogger Perez Hilton as saying: "We're not trying yet. We're revving up the engines. I'm only ready because time's a-ticking.

"If I was 34, I'd wait another year. I want Coco to be helping me with the next one. One child is hard. Two is probably harder."

The former 'Friends' actress is comfortable with her age and her body and had no problems stripping off for the pilot of her new TV show 'Cougar Town', which sees her character Jules Cobb examining her naked body in a mirror.

Courteney added: "I'm not the young one anymore. I'm not going to be the up-and-comer. When you accept this certain thing about getting older - and I'm not saying there's anything wrong - it's just that I'm just not 20 anymore.

"I'm not in my 30s. And that's OK. There's something very freeing about that."

Courteney and David, 38, will star together in horror movie 'Scream IV' which is set to be filmed next year.
