According to an insider, the 42-year-old actress is "house hunting and hoping to find something in the next few weeks. She has looked at places to buy as well as places to rent in the Beverly Hills area."
Aniston, who has dated anyone seriously since John Mayer, is planning to live with new beau Theroux, 39. "The relationship is going extremely well and this is the next step to something they are hoping will be permanent," the insider tells Us Weekly.
The Horrible Bosses actress recently purchased a one-bedroom penthouse in New York City's West Village; the pad's previous owner was star hairstylist Sally Hershberger. An insider confirmed to Us in May that Aniston spent a reported $8 million to purchase both Hershberger's 18th floor apartment and an additional 17th floor one-bedroom in the stone Art Deco building, constructed in 1931. She plans to combine both units for a mega-duplex with 2,700 square feet of interior space and 900 square feet of outdoor space.
