The pictures in question aren't themselves particularly interesting – just a single hand on a mixing desk – but the fact they both shared pretty much identical images at the same time has got people talking that they are recording together in the studio. And we can't help but think that's exactly they're intention.
Perhaps we're jumping to conclusions here, but then again Cara has made no secret for her love of music – not only has she shared her own music on the web, but she has also lent her vocals to the track Pharell contributed to the short Chanel film they both starred in.
So, could we be seeing a collaboration from two of the world's most famous women? Stranger things have happened, and it would certainly be a savvy business move, combining the fanbases of two megastars… the question is, what will the music sound like?
Answers on a postcard, please...
