Wiz Khalifa, Amber Rose — Booty Call Triggered Divorce … But it Wasn’t Cheating

EXCLUSIVE

Wiz Khalifa left Amber Rose weeks before she filed for divorce … and the trigger that sent Amber’s lawyer running to the courthouse was an uninvited 2 AM  household call by Amber … TMZ has learned.

Sources connected with Wiz tell TMZ … the rapper is telling friends there’s a simple reason why he left … “I just didn’t want to be married to her anymore.”

We’re told Wiz went out and got his own place, and the day before Amber filed, she went to his household at 2 AM and found him with another woman … and went nuts.

As far as Wiz is concerned … he wasn’t cheating. He told friends he made it clear weeks earlier the marriage was over.

It’s fascinating … even though Wiz went out weeks before … he listed the legal date of separation on his divorce response as Sept. 22 — last Monday.

We’re told Wiz is also persuaded …  Amber was secretly banging Nick Gun — something they both deny.
