Reports have suggested that the couple will be going their separate ways after their On The Run tour wraps, and some even alleged that Bey had been house hunting for her own place.

We all know Kim LOVES a selfie – she is releasing a book of all her best ones, after all – but last night she uploaded a snap of her and Kanye kissing in an elevator.

She captioned it: "#ElevatorKiss"

Now US reports are saying that this is Kim's way of rubbing it in Beyonce's face that she and Kanye are dong just fine – and a way at getting back at her for ditching her wedding.
