Justin Timberlake’s mom Lynn Harless has joined forces with the mother of her son’s first love in an effort to ensure that Lynne Spears remains an active part of her grandson’s lives.

While Justin is trying to stay out of his ex-girlfriend’s affairs, his mother, Lynn Harless, is getting involved: “Lynn’s comforting Lynne Spears,” says an insider. “But she and Britney always got along well too, so she’s trying to let Brit know that her mom isn’t the enemy,” say a tab snitch.
