On his KIIS radio show last week, Ryan told co-host Ellen K: "I think we could definitely see an update on this story on Monday."
In the evening, Kardashian and West pulled up to Miami Beach's LIV at Fontainebleau club in a stunning gold Lamborghini, emerging as Batman and Catwoman.
Whilst Kanye looked suitably superhero-esque, all eyes were on Kim's black leather-clad curves.
