The recently married 37-year old, who admitted to marie claire last month she has trouble "staying still", reportedly asked creative director Marc Jacobs if she could take part in the show.
"She's a very dear friend so...happy to oblige," Jacobs reportedly said backstage at Louis Vuitton.
It was a decidedly lighter collection this season in comparison to the last, which saw Moss stalking the runway in a bondage-inspired outfit whilst smoking a cigarette.
This time around, models swanned serenely around a decadent carousel in the middle of the catwalk while showing off pastel and almond coloured separates and voluminous dresses.
"We've really got it together," Jacobs said. "Most of what you see in the show makes it to our key stores".
The designer commended his team backstage, saying, "The workmanship on our new basket weave bags is insane. It took six hours just to line up the skins on one coat!"
The collection was reportedly met with high praise from fashion editors, further fuelling the rumour that Jacobs is set to take over the helm of Christian Dior.
"Jacobs refuses to discuss it, although he conceded that his past few shows had become increasingly spectacular - so he'd rise to Dior's tradition of extravaganzas," said the Telegraph UK. "But if he does transfer, he seems to be sending out signals that he'll be doing it on his terms - and possibly keeping his team."
