KEY POINTS:
Britney Spears' family has joined forces with Kevin Federline's family to support her.
The Toxic singer's stint in rehab has brought the two families closer - despite the couple's impending divorce - to support Britney and care for her two young sons.
A source told People magazine: "Everyone is making comments how sad it is that it took this to get everyone together.
"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."
Kevin has been looking after 18-month-old Sean Preston and six-month-old Jayden James, with the help of both families, since his estranged wife checked into rehab.
Meanwhile, Britney is reportedly not coping well in rehab.
She is allegedly frequently breaking house rules at Malibu's Promises rehab facility.
A source told Us Weekly magazine: "She's been getting in tons of trouble. She has been cautioned for being on her cell phone and has even left the centre to go shopping."
The 25-year-old is allegedly angry with her family for saying she needs to get sober, and believes she does not have a drug or alcohol problem.
The source added: "Britney is angry at her family and her manager for pressuring her to enter the program.
"She believes she is suffering from postpartum depression and does not think she has an alcohol or drug problem."
Since entering the clinic, Britney has been seen reading Brooke Shields' book Down Came the Rain about the actress' own experience with postpartum depression following the birth of her first daughter, Rowan Francis.
