Lawrence was left alone on one visit to see her pal and couldn't resist inspecting Kravitz's trophy collection, and she was left embarrassed when the singer walked in on her midway through her monologue.
She tells Britain's Marie Claire magazine, "I was round Lenny Kravitz's house. Anyway, I was all by myself in his home and I looked around and I saw his collection of Grammys. I just couldn't resist, so I went and grabbed one and started giving an imaginary acceptance speech.
"Next thing, I just hear this deep voice from behind me go, 'So, how does it feel, Jen?' I turned around and there's Lenny with his huge bodyguard friend. I was gonna come up with something about polishing it. But, hey, I'm fooling no one."
