She seemed to be in good spirits despite the rumours surrounding her relationship with estranged husband Ben Affleck as she had a chuckle on the Atlanta, Georgia set of the drama.

The Alias actress flashed her intoxicating smile as she sat in the passenger seat of the old four door as she continued work on the faith-based film.

She was casually dressed in character as she rocked a checked white and black blouse along with baggy white trousers.

It was a completely light look for the mother-of-three as she wore a white undershirt and matching sneakers.

Her straight highlighted-brunette tresses were worn down as she wore her regular natural, complimentary make-up on her face.

Jennifer was not alone during the day of filming as she was joined by her on-screen daughter. The two seemingly have a good rapport with one another as they chatted in between takes.

Despite the drama surrounding her split from her husband of 10 years, she was seen wearing a wedding band on set. 

Jennifer appears to be trying to keep life as normal as possible in the wake of allegations her 42-year-old estranged husband is in a relationship with Christine Ouzounian.

The 28-year-old blonde has been pictured out in Los Angeles in recent days as sources claimed to People that she told friends the affair 'has been going on for a long time,' adding, 'Christine is in love with him.'

The magazine also reports that Christine accompanied Ben and the children on their Bahamas getaway last month before Jenner flew separately to join them.

It was during that trip that the Hollywood couple broke the news that they are divorcing after 10 years of marriage.

A friend of Christine's says she left the Bahamas with Ben and attended a charity poker event in Las Vegas with him.

It was apparently while Jennifer was still in the Bahamas that she found out about the affair and was said to be 'livid'.

Meanwhile Us Weekly claims that Christine was fired by Jennifer after she discovered how well the pair were getting on but she remained in contact with Ben and spent time with him in Los Angeles on July 17. 

The actor's team has described the affair claims as 'baseless and untrue'.

And a rep told the New York Post's Page Six: 'The story is complete garbage and full of lies. You shouldn't be able to hide behind "blind sources" and attempt to destroy families going through a difficult time.'

The allegations come following multiple reports that Ben's alleged infidelity led to his split from Jennifer, while it is has also been claimed that his drinking allegedly contributed.

The couple announced their separation a day after their 10th wedding anniversary. They told DailyMail.com in a joint statement: 'After much thought and careful consideration, we have made the difficult decision to divorce.

'We go forward with love and friendship for one another and a commitment to co-parenting our children whose privacy we ask to be respected during this difficult time. This will be our only comment on this private, family matter. Thank you for understanding.'
