Watch the video after the jump. It's been six years since Courtney Love appeared on the 'Late Show' (weeknights, 11:35PM ET on CBS), due in part (we can assume) to her risque behavior -- flashing the host -- on that particular visit. Not that David Letterman didn't enjoy it...

She's clean and sober now, but as Love explained, "I took off my top because Drew Barrymore had done it when she was 19, and I was so out of my mind I thought I was 19."

Letterman responded, "From my point of view, I enjoyed it. I don't want to be what they call an enabler, but... seemed like you were at the top of your game to me."
