Tom Cruise and Katie Holmes isn't the only celebrity parents who want to have more kids in their family. Courteney Cox and her actor husband David Arquette also willing to expand their clan by having another In vitro fertilization (IVF) treatment.

Cox and Arquette, who are the parents of daughter Coco Riley Arquette through IVF, reportedly already had more blood tests to begin the process all over.

"I'm not really ready right this second, but I'll probably do it one more time. I'm planning to do IVF again," the actress-mother said in an interview with Marie Claire magazine. "I used to want to have eight kids. It was such a fantasy when I was younger, because my mother, who was an only child, had four kids. Now, looking back, I don't understand how she did it."

Admitted she once suffered from post-natal depression and that having a baby is hard work, Cox said "I think the baby part - like waking up early - is hard. Really hard. Do I believe in post-natal depression? Yes. Did I have the worst case of it? No. Post-natal depression can be devastating. Luckily, I was able to get through it."
