Grammy award winning R&B songstress Mary J. Blige and Mayor Michael Bloomberg were the star attractions at the The New York Women's Foundation (NYWF) Fall Dinner 2009 the other night held at Manhattan's chic Gotham Hall.

Blige (right) performed at the exclusive event, where guests included socialites Agnes Gund, Anne Bass, Muffie Potter Aston, Sharon Bush, Debbie Bancroft, Jean Shafiroff, Denise Rich, and designer Catherine Malandrino.

Stepping Up Awards were presented to New Yorkers who "serve as role models of courageous leadership, vision and commitment to women and girls as individuals and as partners," including Elizabeth and Herbert Sturz and Sheryl WuDunn and Pulitzer Prize-winning columnist Nicholas D. Kristof.

Established in 1987 as a public philanthropy, the NYWF strategically funds organizations and programs that move women, girls and families towards long-term economic security through individual transformation and systemic change.

Forbes just released its annual Forbes 400 list of the richest Americans, and billionaire Microsoft founder Bill Gates (above) is back on top after briefly ceding first place to Warren Buffett this spring. Gates has a net worth of $57 billion as opposed to Buffett's $50 billion - $12 billion less than he had several months ago before Berkshire Hathaway's stock plummeted 15%. Buffett isn't the only one to suffer a major reversal. The year's biggest loser was Sands casino mogul Sheldon Adelson, No. 15, whose fortune fell $13 billion in the past 12 months - about $1.5 million per hour, Forbes notes - to $15 billion.

Adelson's fellow casino kingpin Kirk Kerkorian, No. 27, was another underachiever, losing $6.8 billion this year. Still, they were both better off than the 33 moguls who fell off the list altogether due to declining fortunes. On the plus side, 31 new plutocrats moved up to take their places, including Facebook founder Mark Zuckerberg, 24, who makes his debut on the list with an estimated net worth of $1.5 billion.

Other Forbes 400 first-timers include fertilizer tycoon Alexander Rovt, car dealer and art collector Norman Braman, and Patrón tequila founder John Paul DeJoria. Meanwhile, New York City's billionaire mayor Michael Bloomberg was the year's biggest gainer, as his net worth jumped $8 billion to a total of $20 billion, snagging him the No. 8 position. Also worth noting among this year's stats:

The average net worth of Forbes 400 members is $3.9 billion.
There are 42 women on the list with an average net worth of $4.2 billion.
For the 2nd year in a row, the minimum net worth needed to make the list is $1.3 billion.
The assembled net worth of the richest Americans rose by only 2%, or $30 billion, to $1.57 trillion this year.

Forbes has come up with a new list of the 10 young women most likely to inherit their mega-rich fathers' fortunes - in short, the billion-heiresses of tomorrow. The final list does not merely represent the daughters of the world's richest men, however; for a true accounting, the magazine started with the daughters of the world's 150 richest people, all worth $6.4 billion or more, but then focused only on those with few or no siblings to divide the loot.

They further narrowed the field by disqualifying those with fathers like Bill Gates who have declared their intention to leave their fortunes to charity instead of their children. Also, they did not include those who have already inherited their money, like the world's richest woman, L'Oréal heiress Liliane Bettencourt.

No. 1 on the Forbes list is India's Vanisha Mittal Bhatia, daughter of Lakshmi Mittal, the fourth-richest person in the world with a fortune of $45 billion. The No. 2 and 3 heiresses are also the daughters of Indian tycoons, while No. 4 is Delphine Arnault-Gancia, daughter of LVMH chairman Bernard Arnault, the world's 13th-richest man with a fortune of $25.5 billion. And clocking in at No. 7 is championship equestrienne Georgina Bloomberg (above), daughter of New York's billionaire mayor Michael Bloomberg. See the gallery for more.

As we mentioned in our Classicist column on Anderson & Sheppard last week, dapper Vanity Fair editor Graydon Carter is a devoté of the bespoke British tailoring firm. He proved the worth of a well-made suit with the black three-piece Anderson & Sheppard number he wore to the Tribeca Film Festival fete that Carter co-hosted with Robert De Niro in Manhattan the other night.

Carter, pictured here with New York's billionaire mayor Michael Bloomberg (one of the guests along with Sigourney Weaver, Harvey Keitel, David Bowie, Jerry Seinfeld and others) looked quite dashing and much more svelte than on some previous occasions -- a fact which we feel is attributable more to A&S' fine tailoring rather than any newfound abstemiousness on the editor's part. After all, he does own one of NYC's trendiest eateries, The Waverly Inn, and we highly doubt he's ever presented with a bill.
