Is Bill Gross really buying Jennifer Aniston's house for $42 million?

That's what Real Estalker has posted, and it's being picked by a WSJ blog and others. Gross and his wife own a bunch of property in OC, Indian Wells and Pebble Beach, so the purchase certainly would be within the realm of possibility. But neither party is talking. The Bev Hills property is a big deal: five bedrooms, seven and a half bathrooms, a gym, a pool, outdoor living room and kitchen, and a staff room. Aniston bought the place in 2006 for $13.6 million, and then rebuilt much of it. From Real Estalker:

We quickly put out a few feelers with some of our most well-informed informants. Within minutes of sending an email we heard back from a plugged-in real estate insider we know-let's call her Chatty Cathy-who floated the name of-are y'all ready for this?-a billionaire mutual fund manager from Orange County named Bill Gross. After a scoot and scout around the interweb and a some drilling down into scads of public property records we found at least one other property in Orange County owned by Mister Gross and his wife-a gal named Sue-that links back to the same Irvine office as the Banana Trust. Coinky-dink? No. We consulted our all but omniscient informant Lucy Spillerguts who was able to confirm with absolute certainty that the buyers are Mister and Missus Gross.
