Jennifer Aniston has turned to her close-knit group of girl friends after allegedly calling off her marriage to boyfriend Vince Vaughn. The actress is reportedly single again and is calling on best pals COURTENEY COX ARQUETTE, Sheryl Crow and volleyball star Gabrielle Reece to help her cope with another broken romance. According to America's Life + Style magazine, Aniston staged a girls-only get together at Cox Arquette's Malibu, California home on 24 July (06) and has been referring to herself as "the new Jen" ever since. Aniston and Vaughn never officially announced their engagement, but US tabloids were rife with wedding plans. The all-girl power meeting was a chance for Crow to officially thank her pals for helping her through her breast cancer battle. In a recent interview, the rocker revealed that Cox Arquette and Aniston were among a small army of pals who stood by her as she faced her health crisis. Crow revealed, "I had this incredible tribe of women just descend upon me and carry me through the whole experience on their backs."
