Los Angeles, September 29 – Jennifer Lopez’s West Side Story took place in Santa Monica on Thursday, when she debuted her J. Lo clothing line with a fashion show at the 23rd Macy’s Passport AIDS fundraiser. In typically understated style, dancers shimmied on the stage in front of a giant backdrop, and Jenny from the block wore a floor-sweeping gown as she walked down the runway at show’s end for her designer’s bow.

Then, she jumped into a front row seat next to husband Marc Anthony, and the two had a ball pointing and laughing at the child models dancing and tumbling in the Mattel Hot Wheels fashion show.

The evening opened with a live auction, and Sharon Stone made the most of her job as auctioneer. The first time Stone’s dress came undone, her assistant stepped in to button her up. It happened again, and she took advantage of the situation, auctioning off the fastening duties for $500.

Pete Sampras got caught up in the auction excitement, and impulsively threw in a private tennis lesson followed by lunch at his house. When pushy auctioneer Stone got the bidding up to $17,500, she brought the champ up onstage, took him aside and asked if he’d throw in a second identical package. Sampras turned to us and muttered, “She’s going to ask for my first-born next”. Stone sold lesson number two for another $17,500.

The evening included several other fashion shows, and Wilmer Valderrama and Venus Williams were on hand. Elizabeth Taylor was unable to attend.
