His 3,049-square-foot Los Angeles home includes three bedrooms and three bathrooms, according to the pocket listing with Emil Hartoonian and Nicholas Siegfried of The Agency. Lambert had previously listed the home for $3.995 million.
The contemporary home features a designer kitchen with marble finishes and a sliding glass wall offering views of Hollywood. The master suite includes a walk-in closet, spa and private terrace.

Lambert won't be far. He bought another Hollywood Hills home for $6.5 million in 2018, the Los Angeles Times reported. It's only about a mile away from this property.
