Aniston and Wilson were inseparable during the filming of Marley & Me, and were flirting on the set in Miami, reported FemaleFirst.
A source on the set revealed, "The hugging didn’t end when the cameras stopped rolling. They were very flirty together, far more than you would expect. In between takes they were hanging onto each other. They are very friendly."
Initially, Aniston was worried about working with Wilson and was surprised at the chemistry between them. According to recent rumours, the 39-year-old actress is dating Brian Bouma, an employee who worked on the set of the film Traveling in Vancouver.
