The stars have repeatedly denied rumours of a re-make or sequel.
Famously highly-strung, Monica would now have discovered a new zen way of life after raising twin babies with no one but Chandler for company out in the suburbs.The rest of the gang don't come around as much when Chandler's not home, because Monica makes them do shots of wheat grass and listen to whale sounds.

After moving out to the suburbs with his wife and twin babies, we're expecting Chandler to have really settled down and, would now spend his days leaving work at 5pm sharp, playing catch in his backyard and wondering aloud: "Could I BE anymore of a good dad?" (credit:Getty Images)

In 'Friends' spinoff 'Joey' we all saw (because, of course, we all watched it) Joey head off to California to chase his acting dream.Well... unfortunately that didn't work out. We're expecting now that Joey lives in Monica and Chandler's basement. We're also expecting they don't know anything about it. (credit:Getty Images)

Presumably working some class of high-power fashion job in-between raising her 12-year-old daughter (yep, Emma would be 12 now...), we think Rachel would be pretty happy with her lot in life, though we might think twice before talking about Brad Pitt around her... (credit:PA)

Staged a successful protest to stop Central Perk being turned into a Starbucks. He can still occasionally be found in the bushes outside Ross and Rachel's house. You know, for old times' sake. (credit:PA)
