Jennifer Aniston and Justin Theroux are reportedly planning to live on separate sides of their new mansion.

Jennifer - who has lived alone since divorcing husband Brad Pitt in 2005 - is apparently having the Bel Air home remodelled so she and Justin can have half of the house each.

A source told the Daily Star newspaper: ''They'll share a bedroom, but they both need their space.

''Jen is building a games room with a pool table, bar and giant TV where Justin can hang out exclusively with his pals.''

The former 'Friends' actress is notoriously generous when it comes to her man, and is believed to have splurged on several lavish presents including a £7,500 leather jacket once owned by James Dean, a £280,000 Genn Ligon painting and two motorbikes, a £20,000 Ducati and a £15,000 Harley Davidson.

Additionally, Jennifer is also said to have spent £600,000 on furniture and artwork for their new Los Angeles home and £470,000 for a feng shui expert to assist with their £6.2million make over on the property, as well as funding the couple's numerous holidays.

A source said: ''Neither Jen nor Justin seem embarrassed that she is the main breadwinner.

''She is in a comfortable position so why not spend money on the man she loves.''
