We all remember when Ross & Rachel gave birth to baby Emma.
It's been 12 years! Feel old?
The little one was portrayed by identical twins Noelle and Cali Sheldon in the final two series, and the siblings look quite different to when they made their debut on the show.
Despite starring in one of the most famous TV sitcoms ever, the 13-year-old siblings haven’t been able to watch many episodes because they are too young!
Speaking to Entertainment Tonight, Noelle explained: “We’ve seen one full episode which was the one where Rachel’s sister babysits.”
They admitted they'll be watching all 10 seasons of the sitcom when they are allowed.
