Britney Spears's family is pulling together to support the singer, who last month entered Promises rehab facility in Malibu, Calif., PEOPLE reports in its upcoming issue.
Her estranged husband, Kevin Federline, along with his mother and Spears's mom Lynne, have forged closer ties while they care for the couple's sons, Sean Preston, 18 months, and Jayden James, 6 months – and help Spears work on her sobriety.
"Everyone is making comments how sad it is that it took this to get everyone together," a source close to Federline tells PEOPLE. "There was a lot of distance between the families but it seems now they all have a common goal, which is to help Britney get better."
