Jed Leiber's House

The BAFTA-winning and Grammy-nominated musician, who is a son of the late songwriting legend Jerry Leiber, owns this unique mansion high in the Hollywood Hills. It is commonly called the "Fortress" and is made almost entirely out of poured concrete.

Leiber purchased the house in 2012 for about $7.2M from headphones entrepreneur and DJ Val Kolton, who had purchased the house for $8M in 2008 from Rockstar energy drink billionaire Russ Weiner.

In 2014, it was reported that the house had been leased to Rihanna.
