Liz Taylor Slept . . . Elsewhere, Actually

The glossy ad for the Watergate's $3.95 million penthouse promises sweeping views, full-length balconies and an A-list pedigree: "Previously the residence of Elizabeth Taylor and Senator John Warner."

Glamorous, huh? Except it's not true -- Taylor never lived with him at the Watergate, said Warner spokeswoman Bronwyn Lance Chester.

When Warner married the violet-eyed movie star in December 1976, he owned two properties: Atoka Farm, a lush spread near Middleburg, and a home at 3240 S St. NW in Georgetown. Taylor fell in love with the Virginia countryside and campaigned throughout the state when her sixth husband successfully ran for the Senate two years later. Shortly after he took office, the couple moved into the S Street house and spent weekends in the country.

Alas, the marriage lasted just six years -- the two separated in 1981 and divorced a year later. The actress fled back to Hollywood while Warner sold the Georgetown property and settled into a bachelor pad at the Watergate: the same two-bedroom, two-bath apartment featured in Long & Foster's Extraordinary Properties and listed by agent Nancy Itteilag.

A bit of real estate hyperbole in a soft market? Itteilag told us she "used information we got from the current owner," and did not return follow-up calls yesterday.

Virginia's senior senator has moved on -- literally and figuratively. He sold both Atoka and the Watergate apartment years ago and married real estate agent Jeanne Vander Myde in 2003; the couple now live in Alexandria.

Deadheads, unite! A private mini-concert Monday night with Grateful Dead co-founder Bob Weir-- originally planned for 50 people -- proved so popular that it was moved to the spacious Kalorama home of Washington Life editor Nancy Bagley. The 60-year-old Weir (graying beard, jacket, socks with sandals) arrived at the bash fresh from Camden Yards, where he sang the national anthem with his current band, RatDog. Weir spent an hour signing posters, performing a few songs and chatting with the 200-plus guests, who skipped the NCAA championship basketball game to hang with the rock legend, chow down on crab cakes, roast beef and fudge cookies, and raise money for HeadCount, a nonpartisan voter registration group.

The concept: Musicians (other HeadCount partners include the Dave Matthews Band, Foo Fighters, John Mayer) herd 18-to-24-year-old concertgoers to registration tables. "The notion is that we could get a bunch of young people involved in democracy -- not politics," Weir told us. "It seems to me more than ever that if people just sit back and let the powers that be run the show, this country will slide inevitably to a plutocracy." Allrighty, then -- but can we still have crab cakes?

Dating: Marla Maples, 44, and Andy Baldwin, early-30-something. She, of course, is the former . . . well, we can't remember what she was before she married Donald Trump (they split in '99); he's the Navy officer who last year starred on TV show "The Bachelor," through which he got briefly engaged to D.C. native Tessa Horst. Weird, right? Is this a publicity stunt? Baldwin, who is reportedly moving to D.C. for a job, told People that Maples "has the mind, body and energy of a 25-year-old."

One week before Pope Benedict XVI arrives in D.C., and if you haven't got an invitation to one of the VIP events . . . well, it's probably not coming.

After a morning reception at the White House, the pope will celebrate his 81st birthday April 16 at a super-exclusive luncheon at the Vatican Embassy on Massachusetts Avenue NW. The guest list is limited to 20 or so (mostly cardinals), the menu Italian (catered by Cafe Milano).

The festivities continue that night at the Italian Embassy, where more than 400 people -- including the current and former U.S. ambassadors to the Holy See -- will attend a party hosted by the Washington National Opera (General Director Placido Domingo is singing at the papal mass on April 17) and Italian Ambassador Giovanni Castellaneta. Very fancy, but the Holy Father is not expected to attend.
