Ronson's Streetside Serenade

The activity outside of Hyde is getting even more bizarre these days -- just ask DJ and Lohan pal Samantha Ronson!

Sam was filling in at the host stand last night when a homeless guy set up shop right next to her -- and started strumming away on his guitar, serenading the DJ.

Though a pretty odd performance, a laughing Ronson was a good sport about it -- and bobbed to the music as he played.
