Munn left her luscious long locks loose and sported sunglasses and a face mask.

She carried a black alligator purse and her phone as she headed to her parked vehicle.

The star of The Newsroom and Six spoke with People last month about finding out she has fibromyalgia. 

‘I wasn’t really sure what was going on with me,’ she explained. ‘I was going through a lot of different ailments for years and not knowing what was happening.’

Munn worked with five doctors from UCLA to try and discover what was ailing her.

It was determined that she was suffering from the autoimmune disorder which, according to the Mayo Clinic, is ‘characterized by widespread musculoskeletal pain accompanied by fatigue, sleep, memory and mood issues.’

It has no cure but medications and things like stress reduction can help alleviate the symptoms.

As a result of the diagnosis, the Oklahoma native said she had to change her wellness routine ‘ pretty significantly’.

‘I had to be super thoughtful about what I put into my body,’ Munn told People.

‘I had to start eating gluten-free, dairy-free and sugar-free — I had to cut out a lot of things that I was used to having every day and things that I really loved.’

She now practices ‘mindful eating’ as well as sticking to regular workouts and exercise.
