Former “Entourage” star Jeremy Piven, whose show “Wisdom of the Crowd” was unceremoniously cancelled last year following poor ratings and cascading allegations of sexual harassment that the actor-producer emphatically denied, is shaking up his bicoastal property portfolio, shedding a beachfront home in Malibu at a steep discount after more than a year and a half on and off the market and putting a sports-star-pedigreed duplex penthouse in New York City’s Tribeca neighborhood up for sale at nearly $7.8 million.

The former “Mr. Selfridge” star, who shelled out $6.8 million for a contemporary residence high above L.A.’s Laurel Canyon over the summer of 2017, sold his beachfront getaway along Malibu’s prestigious Malibu Road earlier this year for $6.6 million, almost twice the $3.5 million he paid in 2004 but substantially below the final asking price of $7.75 million. With more than 4,400 square feet over three floors, the four-bedroom and 3.5-bathroom beach house offers adjoining living and dining spaces that spill out through a wall of glass sliders to a slender, sunset-facing deck with a free-standing spa. An en suite guest bedroom and screening room share the second floor with an ocean-facing master suite. A sprawling lower-level entertaining room offers a wet bar, a dry sauna and direct access to a partly covered wrap-around deck that hovers just above the sand with cushioned, built-in sunbeds.

Meanwhile, Piven’s generously terraced Manhattan penthouse, purchased in 2011 for almost $4.7 million from pro baseball legend Mike Piazza, measures in at a tad more than 3,000 square feet with two bedrooms and 2.5 bathrooms. A double-height space that does double duty as the foyer and dining room is flanked by a corner living room with fireplace and open-concept galley kitchen. Full-height glass panels glide open off the kitchen to a combination office/gym. The lower-floor bedroom has a full wall of built-in storage and a small bathroom while the second- floor master bedroom includes a party-sized shower with a wall of glass that opens to a private, planted courtyard. A potentially exposing, glass-floored catwalk spans the dining room to a roof deck with built-in barbecue, outdoor television and corkscrew staircase to a second terrace with wrap-around city views.
