Sienna Miller, Jamie Burke Party in N.Y.C.

Okay, so even The Hollywood Gossip gets it wrong sometimes.

And we weren't all that wrong in this case. Just slightly.

Much like last fall, when we originally reported that Britney Spears' one-night boy toy was Jonathan Rotem (he goes by J.R. Rotem), we've made a similar blunder in regards to Sienna Miller's new man.

In fairness to us, Sienna Miller's crazy life is often hard to keep track of. So many quotes. So many men.

Anyway. Jamie Burke (who we originally called James Burke) was performing with his band, Bloody Social at the New York City club The Pitt this weekend.

The actress, who wore a silver tunic, and who loves some drugs, arrived with Burke and then hung out with friends in a corner banquette.

When the show started at midnight, Sienna Miller pushed through the crowd and stood front-row center as she grooved and sang along during the performance.

Before exiting the stage, Burke gave Miller a hug. We can only hope she forces him to get a "SM" tattoo on his wrist, a la Nick Zano and Kristin Cavallari.
