We first got a glimpse into Blake Lively and Taylor Swift's friendship during the singer's Fourth of July celebrations in Rhode Island.

Following a star-studded two-day extravaganza, the Gossip Girl singer and her new BFF were later photographed perched atop of their partners' laps (Ryan Reynolds and Swift's then-boyfriend, Tom Hiddleston), with a an incredibly awkward-looking Ryan whose face seemed to say he'd been forced into the most cringe-worthy PDA moment.

Since then, Swift and Lively's friendship has gone from strength-to-strength, with the 27-year-old reportedly introducing her boyfriend, actor Joe Alwyn, to the actress and her hubby this summer, and the 30-year-old quoting Swift's lyrics in her recent birthday post.

And now it seems the 'Look What You Made Me Do' singer has upped the ante on the duo's friendship, with fans speculating that the star invited Blake's eldest daughter, James, to feature on her latest single 'Gorgeous'.

With many fans claiming Swift's new single is about Alwyn, others have taken to social media to suggest the young child saying the word 'gorgeous' at the beginning of the track is the two-year-old daughter of Reynolds and Lively.

Other 'Swifties' suggest the voice could be that of actress Jaime King's son - and Taylor's godson - Leo.

To be fair, it would make sense if James was on the single, given than Taylor reportedly visited Blake and Ryan when they were in the hospital for the birth of their second child and spent time together at Swift's Rhode Island beach home in July.

In true Swift fashion, the star is yet to confirm the rumours, but hinted in a recently deleted Tumblr comment that '300 people know'.

Oh to be one of those lucky 300.
