Friends fans will no doubt remember Ross and Rachel's baby and her obsession with 'Baby Got Back'.
Emma Geller-Greene was, of course, the daughter of Ross Geller (David Schwimmer) and Rachel Greene (Jennifer Aniston) - first appearing in the finale of Season 7.
Identical twins Noelle and Cali Sheldon each took turns playing Emma during their time on the show.

And before we carry on, it doesn't feel right without mentioning Matthew Perry.
The Friends actor, who famously played Chandler in the hit series, was found 'unconscious in a stand-alone Jacuzzi' at his Los Angeles home on 28 October.
He died at the age of 54 from 'acute effects of ketamine', according to his autopsy, and his death was ruled an 'accident'.
His family confirmed the tragic news in a statement, saying: “We are heartbroken by the tragic loss of our beloved son and brother. Matthew brought so much joy to the world, both as an actor and a friend.

"You all meant so much to him and we appreciate the tremendous outpouring of love."
And whilst fans of the show are still mourning his loss, it's important to remember that although Perry is no longer here, Chandler isn't going anywhere.
Mr Bing was in fact Emma's godfather on the show and over 20 years since the last episode, Friends fans are all making the same joke.
One of the most memorable storylines featuring Emma was from the season 10 episode ‘The One with the Cake’.
Ross and Rachel decided to throw a birthday party for Emma, who just wouldn't wake up from her nap.

On the day, the parents decide to make a home video, in which a disgruntled Chandler tells the camera: “Hi Emma, it’s the year 2020. Are you still enjoying your nap?”
And taking to social media in 2020, Noelle responded in the best way possible.
She posted: “Just woke up from the best nap of all time, happy 2020!! (ft. my poorly done Photoshop) Hope everyone has an excellent year full of family, friends, and laughter!!”
One person commented: “It’s wild how you actually look like you could be Jennifer Aniston and David Schwimmer’s child as an adult in this picture!”

“About time you woke up from that nap Emma!” another joked.
While another said that they could 'pass for Ross and Rachel's daughter'.
Nowadays, the twins are 21-years-old and fans can't get over how fast it's gone.
"Sorry, but you will be always Emma for us," one commented.

A second added: "I hope that Jen and David see this photo."
And a third said: "EMMA is all grown up."
