Earlier this week Playboy publishedvintage photos of an excavation project along with a blueprint showing a series of tunnels connecting the infamous residence with various celebrity homes in the surrounding area.

According to the article, when asked about the photos of the construction site the new Playboy Mansion general manager reportedly said, “that’s probably when they built the tunnels in the 70s.”

“We’ll go ahead and assume they’re talking about Jack Nicholson, Warren Beatty, Kirk Douglas and James Caan — all of whom lived near the Playboy Mansion during the late 1970s and early 1980s,” Playboy reported.

According to the article, the partial tunnels were closed up in 1989 when Hugh Hefner married then-Playmate Kimberley Conrad.

Playboy reached out to the publicity representatives for Nicholson, Caan, Douglas, and Beatty, and has yet to receive a comment.
