Jennifer Aniston may not be a biological aunt to seven-year-old Coco Arquette -- the daughter of Courteney Cox (Jen's bestie) and David Arquette -- but Jen was named her godmother in 2005. The two are close and Aniston once told Yahoo that she tries to spend a lot of time with the little gal: "Coco calls me Nuna. I see her almost every weekend and she's really turning into such a lovely little girl. She's sweet, funny, and creative and we just sit there in awe of her." During this past holiday season, Aniston (pictured with Cox and Coco in Anguilla on Jan. 7, 2005) was on-hand to spend time with her goddaughter, who was going through a rocky time with the separation of her parents in November. A source close to Cox told People, "Both Jen and Courteney are tired after a long year. They celebrated Christmas (with) each other and just focused on making things special for Coco."
