Former Playboy centerfold Kristina Shannon fell HARD multiple times, and damn near spilled right out of her top during a wasted night on the Sunset Strip.
Our photog caught Kristina mid-tumble as she was leaving the famed Chateau Marmont Thursday night -- and her poor friend was struggling to keep Shannon upright.
One half of the Shannon twins did manage to tell us about her new twins -- she says she got new boobs ... which she proceeded to flaunt, but that's not even the best part of this video.
Watch Kristina attempt to get from the curb to her car. It's epic ... as in #epicfail
