In a video for Architectural Digest accompanying her August cover story for the magazine, the 24-year-old supermodel takes fans on a tour of her house, stopping to point out pieces by contemporary artists including James Turrell, Barbara Kruger and Tracey Emin.

The latter’s 1999 neon sculpture “Very Happy Girl” serves as the focal point of Jenner’s master bedroom; it features several measurements alongside the message, “Glad to hear you’re a happy girl.”

“I’m pretty sure the measurements are an ex-boyfriend of Tracey Emin’s penis size, and then the message at the bottom is to his new girlfriend, ‘Glad to hear you’re a happy girl,’” the star said in the clip. “Because he has a really big penis, I believe.”

A New York Times review of Emin’s 1999 exhibition “Every Part of Me’s Bleeding” confirms that the British artist “announces the dimensions of her [then-]current boyfriend’s penis” in the racy piece.

One of three total editions of “Very Happy Girl” sold for approximately $63,320 in a 2007 Christie’s auction.
