Today's edition of "Which celebrity's house is this?" involves the 3,981-square-foot house at 1663 Summitridge Drive in Beverly Hills, Calif., which sold in May for $4,187,500. The buyer was something called the Anthony Trust, and the trustee's name on the deed was William Harper. You may recall that Harper has represented many celebrities (mostly in the music business) over the years, including Sheena Easton, Joel Grey, Kris Kristofferson, Trent Reznor and Toni Braxton. That's what leads us to believe that the buyer of this Summitridge Drive house was a celebrity. Built in 1966, the house sits on a fascinating, oddly shaped, 0.57-acre lot, with something like eight sides to it. Originally listed for $4,595,000, the five-bedroom house has four and a half baths, a two-story living room, light-filled rooms, city and canyon views, a master bedroom suite with a large balcony, and a new custom pool with a sound system, according to listing information. So, dear readers, tell us -- does anyone know which celebrity's house this is? Oh, and confidential to tlp333: yes, we promise, one of these days -- soon -- we'll throw together all of the "Which celebrity's house is this?" items along with the owners we've been able to identify. Stay tuned.....
