Courteney Cox and David Arquette's 12-year-old daughter, Coco, has grown up before our very eyes.
Coco accompanied her famous mama and the actress' friends to the star-studded ALS Association Golden West Chapter Los Angeles County Walk at Exposition Park in Los Angeles on Sunday, where she looked adorable wearing matching "Team Nanci" red tee-shirts with the A-list squad. Cox, as well as Reese Witherspoon, Jennifer Garner, and Renee Zellweger, all came out to support their mutual friend and famed power publicist Nanci Ryder, who suffers from the incurable disease.

PICS: Celebrity Mother/Daughter Doppelgangers

Coco went on the walk aside Courteney and Reese -- who has her own 17-year-old lookalike daughter, Ava -- looking like a typical pre-teen playing with her phone.

This isn't Coco's first time in the public eye. In July, she starred in a music video for Irish singer-songwriter Foy Vance's "Coco." Foy met Courteney through the actress' boyfriend, Snow Patrol rocker Johnny McDaid.
Last April, Courteney gushed about her only daughter during her appearance on The Ellen DeGeneres Show, when she revealed Coco sang at her dad David's wedding to former ET correspondent, Christina McLarty.
"She's a really good singer," Courteney said. "I don't know where she got it."
