Fresh from their epic Instagram collaboration, Miley Cyrus and "dumb fuckin' bitch" Avril Lavigne are both fashion mag cover girls this week.

Miley's fronting Elle's annual 'Women In Music' issue, which was covered by Rita Ora, Rihanna, and Gwen Stefani in recent years.

Meanwhile, world's most famous Canadian Avril is on Nylon Thailand's cover -- no surprises there considering how successful she still is across Asia. And before you make snarky jokes about her not being able to land the American cover, Avril actually did it last year to promote "Here's To Never Growing Up."

Check out both covers in full below.
