Jennifer Aniston and Justin Theroux have been on a double date with Tom Hanks and his wife Rita Wilson.

The two couples went for dinner at Los Angeles restaurant Katsuya Brentwood on Wednesday night (04.04.12) and spent over two hours in the eatery laughing and joking together.

A source told People: ''They all appeared to be really enjoying each other's company and sat at a private booth. It was a fun sake and sushi double-date between two super power couples.''

Jennifer, 43, has been busy in recent weeks getting the couple's new Los Angeles home ready to move into, while Justin, 40, has been filling his time with work.

The pair have been in a relationship for almost a year and recently made the commitment to live together.

Former 'Friends' star Jennifer - who was previously married to Brad Pitt, who is now in a long-term relationship with Angelina Jolie - is believed to have spent $1 million on furniture and artwork for the house and $750,000 for a feng shui expert to assist with the $10 million makeover on the property.
