Liza Minnelli was on 'Late Night' (Weeknights, 12:35AM ET on NBC) talking about her latest album, and she dropped a little bombshell on Jimmy Fallon. She said one of the songs on the album makes her think of him.

She then broke into 'You Fascinate Me So,' serenading the late night host.

Now, we've seen women sit or lie on furniture while singing, but we've never seen the man they were singing to do so. Nevertheless, Fallon was apparently so mesmerized by the performance that he couldn't bear to be as far away from Minnelli as it would take him to go around his desk.

So he clambered over it.

Minnelli never broke stride, standing as he got on her side and continuing the performance. Sure, Minnelli may be 28 years older than Fallon, but it must still be quite a thrill to have a legend associate one of her songs with you.
