The couple were heard screaming at each other in the street. 

Ekaterina apparently screamed:

"I'm going to kill myself. You are going to find me dead."

To which Ronnie replied:

"Fuck off home you slut."

What a silver tongued charmer. No wonder the Stones attract such lovely young ladies even at their ages. The old 'treat them mean keep them keen' maxim is clearly a huge success.

Ronnie threw Ekaterina's clothes from the balcony of his house and the police were called. He's now moved out into a flat. That'll teach him.
