Who does Courtney Cox blame for the lack of a Friends reunion?

Courteney Cox has hinted that her former on-screen brother could be to blame for the fact that the Friends cast never meet up together.
The actress played Monica Geller in the long-running sitcom alongside David Schwimmer as her brother Ross, Jennifer Aniston as Rachel Green, Matthew Perry as Chandler Bing, Matt LeBlanc as Joey Tribbiani and Lisa Kudrow as Phoebe Buffay.
She told Yahoo! that despite efforts for them all to hang out together just like in the show, one Friend was holding things back.
She explained: “We’ve not really had a Friends reunion. We’ve gotten about 80 per cent there but there’s always one person that flakes at the end.”
Asked if she was talking about David, she replied: “I’m not going to name names. But it may not be Schwimmer.”
Courteney was less enthusiastic when the subject of an on-screen reunion of the series, which ended in 2004, came up.
She said: “Dear Lord, let it go people! We’re not doing it. It’s just not going to happen.”
