There's Dan Snyder, Abe Pollin, Ted Leonsis and now D.C.'s newest sports owner -- Mark Ein. The multimillionaire bachelor maintained a relatively low profile until he bought the new World TeamTennis Washington Kastles (with Serena Williams, no less); now folks will be sucking up to him for tickets to this summer's matches. Things to know about the 43-year-old venture capitalist:

* Chevy Chase boy made good (Wharton, Harvard), founded investment companies Venturehouse and Capitol Acquisition; won't say exactly how rich he is. "Some things are better kept private, don't you think?" Ein said yesterday. No -- but he still wouldn't tell us.

* Never married; dating on-and-off girlfriend (tech exec Sarah Rosenwinkel) for years. Pals around with entrepreneurs like Leonsis (Ein's one of the exec producers of Ted's documentary about homeless people playing soccer) and Raul Fernandez.

* Pretty good with a racket (was captain of Bethesda-Chevy Chase High School team) and plays lots of pro-am matches; skis (black-diamond slopes), has season floor seats at Wizards games.

* Favorite band ever: U2. Yes, of course, he's met Bono.

* Lives in D.C.'s Palisades neighborhood, owns summer house in the Hamptons and N.Y.C. pied-a-terre; bought Katharine Graham's Georgetown mansion in 2002 for $8 million. "I still own it, I still love it," he told us. "I just haven't gotten around to moving in."


* Our reigning American Idol had a rare overseas summit yesterday with the president. In a gathering at the U.S. ambassador's residence in Accra, Ghana, Jordin Sparks sang the national anthem for an audience that included President Bush and wife Laura, midway through their tour of Africa. (POTUS cheered but did not sing along, our colleague Peter Baker reports.) Bush praised Sparks for efforts by her and the TV show to raise funds to fight malaria: "She has got great compassion and a big heart."

* Due-any-second-now Jennifer Lopez has signed a deal selling exclusive rights to the first photos of her twins to People (in this hemisphere) and OK! magazine (overseas), the Associated Press reports. Advertising Age reported that negotiating prices ranged as high as $6 million; the magazines would not confirm.


After a six-month probe, federal investigators have tracked nearly $50 million in funds embezzled from the D.C. tax office -- but still no sign of that darned Louis Vuitton bag!

Area fashion conspiracy theorists have long speculated that the tax scam probe might ultimately solve another local mystery: the identity of the unknown D.C. woman who purchased the extremely rare and arguably homely $52,500 Tribute Patchwork bag, sewn together from the pieces of 14 other LV bags. After all, the woman at the center of the tax-office scandal, Harriette Walters, allegedly owned hoards of designer bags and shoes and had reportedly dropped five figures on one fancy tote.

Alas, repeated inquiries by The Washington Post (we even circulated photos of the bag among investigators) have turned up no sign of it anywhere in the Walters stash. Which means the weirdo mystery Frankenpurse is still at large. If you see it, do not attempt to approach it on your own. E-mail us at


"No girlfriend. No wife. We gotta hook the Gutt up. The Gutt needs a date!"

-- Steve Guttenberg, telling about his love life -- which may explain why he signed up for "Dancing With the Stars." The 49-year-old actor ("Three Men and a Baby") will compete against Priscilla Presley, Monica Seles, Kristi Yamaguchi, Jason Taylor, Penn Jillette and Marlee Matlin.
