Instagram user KyledeVolle uploaded the pic of Mossy and Reets locking lips, writing: "My 2 fav blondes @ritaora #TheMoss x"
Rita went all matchy-matchy in a head-to-to tartan Moschino trouser suit, bow tie and ghetto gold bling (yep, it sounds like a fashion fail, and guess what? It was).
Kate, meanwhile, was all kind's of cool (as ever) in a studded velvet cape, matching diamante top, skinny jeans and suede stiletto boots.
And let's not forget Georgia May Jagger, who practically stole the show in her sassy sequin 20s-style minidress and HUGE curls.
Mossy fan? Course you are...
