Peggy Siegal invited a media-heavy crowd to the Oak Room last night to watch the Super Bowl. Sports Illustrated editor Terry McDonell was in attendance (apparently, budget cuts prevented him from flying to Tampa in person); and some folks, such as former HarperCollins chief Jane Friedman, left, even donned 3-D glasses to fully appreciate the commercials. Others on hand for the festivities: Richard Johnson, Ron Perelman, Dan Abrams, Dave Zinczenko, Joanne Lipman, Charlie Rose, George Rush, Richard Meier, Cece Cord, Kate Betts, Gay Talese, Rocco DiSpirito, Chuck Scarborough, Francine LeFrak, Andrew and Nancy Jarecki, Ron Delsener, Ken Auletta, Larry Gagosian, Lewis Lapham, Steve Kroft, Lloyd Grove, Morgan Entrekin, Ann Dexter-Jones, Harry Smith, Liz Smith, Cynthia McFadden, and Felicia Taylor.

Who would have guessed there was so much demand for pubic hair dye? Nancy Jarecki's Betty Beauty, which produces "specially formulated color dyes for the hair down there," has filed suit against a competitor called Smart Beauty for copying its thong-shaped logo as well as "content" from its "instruction sheet."

Business can't be going well for Betty Beauty, the line of pubic hair dye created by Nancy Jarecki, the socialite wife of Moviephone creator Andrew Jarecki. Last year, Jarecki's company earned fawning coverage from Vanity Fair and was advertising in some of the most upscale salons in town. Now Betty Beauty is advertising inside subway cars, right alongside those ubiquitous ads for Dr. Zizmor and Spanish-speaking personal injury attorneys. Jarecki says her company is paying $10,000 for 50 underground ads featuring euphemistic taglines and no mention of what the product is actually used for. So why the new marketing approach? You can blame the tough economy (pink pubic hair dye is always to first to go!) or the omnipresent Brazilian waxing trend (does anyone have any public hair left to dye?). But you can blame Nancy herself when that creepy guy on the 6 starts asking whether your carpet matches the drapes.

The wife of director and Moviefone mega-millionaire Andrew Jarecki, socialite Nancy has plenty of cash to throw at pet projects like Betty, her line of pubic hair dyes. Yes, really.
