The couple separated due to the distance between them as Lowndes is based in the US for her acting work, while Evans lives in Britain.
"It was a mutual decision and Jessica and Thom have been on and off for quite a while now. Jessica works mostly in America, while Thom's modelling work is in Britain," dailymirror.co.uk quoted a source as saying.
"They have realised it is totally unfeasible trying to maintain a relationship from different sides of The Pond," the source added.
However, the couple has not ruled out the possibility of getting back together.
"They have hardly seen one another of late. They are still friends and haven't ruled out a reconciliation in the future, if things pan out differently," the source said.
Evans was previously in a relationship with actress Kelly Brook for over two years. They parted in February this year.
