Could Coco Arquette have a little bro or sis sometime soon?David Arquette says he and wife Courteney Cox are considering expanding their family.

“I don’t know. I mean, it takes a lot for us to do it, so maybe adoption,” Arquette, 38, said on The Bonnie Hunt Show. Cox, 45, underwent in-vitro fertilization to have Coco at age 39.

Added Arquette, “Listen, I like practicing as much as possible! But it’s hard… I’m exhausted!”

Late last year, the National Enquirer reported the couple were in the process of adopting, which her rep called “a complete fabrication” at the time. Meanwhile, daughter Coco is growing up to be just like her mom, Arquette beams.

“She’s a little messy so that’s sort of on my side, but she’s very strong-willed which is very Courteney-like,” he says.

“We got her a flute recently and she is just walking around [pretending to play],” he adds. “We’re jammin’ a lot, a little Jethro Tull.”
