Since the late 1990s, supermodel Cindy Crawford and restaurant, bar and booze entrepreneur Rande Gerber have owned a magnificent, multistructure oceanfront compound along Malibu’s scenic and fashionable Encinal Bluffs. Now, so swears superstar real estate yenta Yolanda Yakketyyak, the uncommonly comely couple have forked over — via trust in a hush-hush off-market deal that went down earlier this year with almost no tongue-wagging by the real estate obsessed hoi polloi — a gasp-worthy $50.5 million for the 5.9-plus-acre estate next door. (For the record, an extensive cross-reference of property records by this property gossip does point toward the Crawford-Gerbers as the new owners.)

The two-parcel spread had been discreetly owned by a recently deceased biotech tycoon who bought it in 1997 for $9.7 million, according to digital documentation, and according to the L.A. County tax assessor, the estate includes a four-bedroom quasi-Mediterranean main house of not quite 5,300 square feet, a separate one-bedroom and one-bathroom guest cottage, a tennis court and a swimming pool.

The Encinal bluffs, beyond Broad Beach at the western reaches of Malibu, are home to a number of estates owned by successful showbiz sorts, such as Marcy Carsey — who unloaded another of her several Malibu estates earlier this year for $60 million to Jimmy Iovine. Brad Pitt owned a glassy modern house that leans out over the bluff that he sold in 2011 for $12 million to Ellen DeGeneres, who, as she’s wont to do, flipped it six months later for $13 million to direct-marketing mogul Bill Guthy, who shills a slew of celeb-endorsed beauty products including Crawford’s anti-aging line.

In addition to their expanding bluff-top compound, the Crawford-Gerbers own another oceanfront cottage in Malibu that occasionally pops up for rent, and last year they dropped $6 million on a bedraggled Point Dume property they plan to do over from scratch and sell off. It looks like late last year, they covertly dumped a fairly remote, 23-acre former children’s camp in the mountains above Malibu and, as far as we know, the couple continues to own a beachfront home in Cabo San Lucas that sits right next door to one owned by tequila business partner George Clooney.
