Actress Jennifer Garner, who has admitted her former husband and actor Ben Affleck into a rehab, is reportedly helping him just for the sake of their children.

A source told US Weekly that the 46-year-old "Peppermint" actress is helping the Oscar winner for the sake of their three children -- Violet, Seraphina and Samuel. "The beauty has no interest in getting back together with the 'Argo' star even though they have been dragging their feet on finalising their divorce because overall she doesn't agree with his decisions," the source added.
