Turns out the Instagram photo Courteney Cox posted with Aniston and Matt LeBlanc over the weekend was from a full Friends cast reunion dinner. Aniston told Howard Stern on Monday that the entire cast gathered at Cox's house for dinner since David Schwimmer was in town. Stern, who was broadcasting from Los Angeles for the first time since the 1990s, asked Aniston about a potential Friends reboot. “If there was a reboot of the show, it wouldn’t be even close to as good as it was,” she explained. “It would ruin it.” This was Aniston's first visit to The Howard Stern Show since 1989, when she was a 20-year-old "NutriSystem Girl."
