Hot stuff! I mean, when you're dating a model, this is what you get and we imagine Kristen Stewart's not complaining! The Twilight star and Miley Cyrus' ex Stella Maxwell strutted down the streets of Los Feliz, on Wednesday, Stella showing some serious skin!

Maxwell wore short denim cut-offs that revealed a bit of CHEEK on the back side ... while KStew kept it cool in her usual cropped white tee and jeans.

Kristen's face is gonna be around a LOT more the next few months, as her Charlie's Angels poster has just been released ... and the film doesn't even hit theaters until Nov. 15!

The film is directed by Elizabeth Banks who also stars as the unseen boss Bosley. Stewart is the character Elena -- a highly-skilled secret agent, of course. Check out the poster and the trailer below!
