"Joey is many things: He's a womaniser; he is into his food; but he's also a very loyal friend," Knox continued.
"So Joey would never go for Rachel because that would be devastating for Ross. But in this case they went for it because, I guess, they thought they would get some interesting storylines."
But LeBlanc wasn't the only member of the famous cast who disapproved of the blossoming relationship, as Aniston also made sure to voice her opinions.
Author of 'I'll Be There For You: The One About Friends', Kelsey Miller, revealed in her book that Aniston made sure that Joey and Rachel's attraction was purely physical.
"Aniston wanted it to be made clear that Rachel was not in love with Joey, but was just attracted to him," Miller wrote. "It had to be a crush, and it had to be more funny than emotional, otherwise, this arc would go from risky to unwatchable."
But we may finally be able to check in on Ross and Rachel's relationship with speculation rife that the cast are set to reunite.
According to The Hollywood Reporter, an unscripted special is in the works to commemorate the show's 25th anniversary in 2020.
"Listen, we would love for there to be something, but we don't know what that something is," the actress hinted. "So we're just trying. We're working on something..."
Until then, we have our Sunday Netflix binge to rely on when we're in need of a good old catch up.
