Liza Minnelli Crashes SATC 2, Has Mystery Star 'Sobbing Like a Baby'
We already knew Liza Minnelli would drop into Sex and the City 2 for a rendition of "Single Ladies." But according to one actor who shot the film's big wedding scene with her, it was one of her mother's songs that stopped the show. "After the shoot, she said, 'I would like to have everyone's attention,' and they pulled out a stool for her at the piano and gave her a mic and she sang a favorite of her mother, Judy Garland. She said, 'Thank you for letting me play with you guys,'" said Nicholas Rodriguez. "It was so heartfelt and genuine. I got choked up and several people were sobbing like a baby, but I'm not going to name names because he might be really embarrassed." That's your cue, Movieline readers!

So what? Liza pulls this trick in every single performance she does nowadays. I think it was written for the show they just filmed in Las Vegas.
My guess is Michael Patrick King; he's really in touch with his feminine side.

She's Liza. She's allowed.
David Eigenberg? (While wondering why HE doesn't have a hit show like Handler's "Californication"?)
"I was Steve, goddamnit! Women loved me!"
Chris Noth. Big (groan) cry-baby underneath that tough facade if ya ask me.

Exactly.
