Wiz Khalifa WASTED with Chicks ... I'm Not Talkin' Amber Rose Tonight! (VIDEO)

Wiz Khalifa stumbled out of a Hollywood club just before 2 AM Wednesday, and his posse railed at our photog for daring to ask the question Wiz himself raised about Amber Rose being a bad parent because she stays out too late.

Wiz was feeling no pain as he left Emerson Theatre. TMZ broke the story ... he's gearing up for a custody fight, claiming Amber Rose cares more about partying than parenting.

No doubt he has every right to party when he isn't taking care of 1-year-old Sebastian, but listen to the outrage from his friends when the subject is raised.

Meanwhile back at the ranch Trinidad Carnival, Amber Rose is partying it up in barely any clothing.

Thank God for nannies.
