Everyone in the world knows exactly who Jennifer Aniston is - or isn't - dating, so we can see why David Schwimmer might be a bit miffed that even his old co-star didn't know his fiance's name.
Apparently a wedge was driven between the former cast-mates when Jen appeared on the couch with David Letterman and joked that she had "no idea" who the actor was marrying.
Since David has been with now-finance Zoe Buckman since 2007, he was reportedly upset by her lack of interest, with a source revealing to The Mail On Sunday:
"David was not impressed that one of his supposed friends didn't know who he was marrying.
"He has been with Zoe for a couple of years and was offended Jen couldn't remember her. He hasn't been taking her calls."
We take it Jen won't be maid of honour at the wedding then... If Ross and Rachel could work through their problems, we're saw Jen and David can.
