On Friday, Tesla CEO and occasional troll Elon Musk made waves on Twitter once again, declaring that he was selling almost all his physical possessions — including his luxury real estate portfolio.

The billionaire appeared to double down on the promise over the weekend, listing two of his Bel-Air homes for sale on Zillow for a combined $39.5 million. Or did he?

Musk owns a handful of homes on the Westside of L.A. and bought the two Bel-Air properties in separate transactions in 2012 and 2013 for $17 million and $6.75 million, respectively.

The houses, which are adjacent on Chalon Road, include the longtime home of comic Gene Wilder, a ranch-style abode that is apparently up for grabs at $9.5 million. The other residence was built in 1990 and has more than 20,000 square feet of space with a two-story library, a wine cellar and a theater. Its asking price is $30 million.
