The documentary has been previewed by the Daily Mail, and an article about the interview was written by the filmmaker, Daphne Barak for the tabloid. Photos of the Federline family, including with their father, Kevin, and other family members are shown, including Spears' other son, Sean Preston, 16.

Jayden Federline reportedly said that despite choosing to not see his mother for several months, he hopes time will heal their family.

"I love you a lot," Jayden Federline said of his mother. "I hope for the best for you. Maybe one day we can sit down like this and talk again."

In Spears' post, she wrote, "I say to my son Jayden that I send all the love in the world to you every day for the rest of my life !!!! My love for my children has no boundaries."

Federline reportedly addressed the challenges both he and his older brother, who did not do an on-camera interview for the documentary, have felt in recent years.

"We've both been through so much pressure in the past that this is our safe place now, to process all the emotional trauma we've been through to heal, heal our mental state," Federline reportedly said in the documentary.

Spears seemed to respond to those specific comments in her post, writing, "It deeply saddens me to know his outcry of saying I wasn't up to his expectations of a mother."

The pop star does not have custody over her sons. This right was granted to Federline following their divorce in 2006 and her very public breakdown afterwards.

For most of their lives, Preston and Jayden have lived with Federline, his wife Victoria and their children, including Federline's older children from a previous relationship.

Spears' Instagram post comes days after the star posted and then made private a 22-minute audio clip on YouTube in which she addressed her conservatorship and the alleged abuse she says she was put through by her family.

In the interview, Jayden also claimed that his grandfather, Jamie Spears, "doesn't deserve all the hatred he is getting in the media."

"At first [Jamie] was just trying to be like any father, letting her pursue [her] dream of becoming a superstar," he says.

"But I did think maybe the conservatorship went on too long. [That's] probably why my mum was very angry about the whole situation – she was working for too long and I personally think she was. She should have taken a break and relaxed."

"I love him, with all my heart. He was just trying to be a father," says Jayden.
