(Cover) - EN Showbiz - Jennifer Aniston and Justin Theroux enjoyed a dinner date in Washington D.C. last night and apparently seemed very much in love.

The 42-year-old actress and her boyfriend got cozy over a meal at Fiola restaurant on Pennsylvania Avenue.

An eyewitness told People magazine that the pair were "very, very cute together".

They were not alone however and were joined by a Lifetime television executive as well as Jeanne Tripplehorn and Patricia Clarkson who are all involved in the channel's film anthology, Five.

Jennifer directed one of the segments which will highlight the trauma cancer victims face while going through treatment.

"They were very cutesy," the insider added. "They were paying attention to each other. They ate the same thing."

The pair were seen going shopping for cleanses recently maybe as a result of the frequent late night dinners they have been having in New York where they are currently living.

A source told In Touch that the couple appeared interested in doing a health cleanse together. (C) Cover Media
