Courteney Cox's daughter, Coco Arquette, is growing up before our eyes. Earlier this month, the ladies popped up at pal Ed Sheeran's charity concert in London, and we can't believe she's a teenager now. Coco — who Courteney shares with ex-husband David Arquette — is 14 years old now, and shares a very special bond with her mom. In fact, Coco recently told People that Courteney has taught her "so much" in her 14 years. "If a stressful situation is going on, she helps me contain my stress and make me feel better," Coco said. "She's taught me a lot about how to be a stronger person in general." Ahead, take a look at some of Courteney and Coco's sweetest mother-daughter moments.
