Federline, 45, has sole custody of Sean Preston, 17, and Jayden James, 16, and is moving from Los Angeles with his kids and wife Victoria Prince. They are allegedly renting a place while they look for a more permanent home.
It is believed that Federline urged his sons to see their mum prior to their relocation, but isn’t going to force them to do so.
Insiders also say that Federline is relieved that Spears hasn’t contested their move in court and feels she has done the right thing by letting her sons relocate.
Federline’s decision to make the move to Hawaii first came to light in May, with sources revealing at the time that Spears was supportive of it.
The insider said that Spears has “always been a loving and supportive mother” and has never disputed their decision to move - despite her ex threatening court action over a reported failure to respond to the relocation request.
The insider said: “Britney loves her children, has always supported them, and wants them to be happy.
“Putting aside that she is an icon, loved and respected by millions throughout the world, she has been a loving and supportive mother, faithfully supporting her children.”
The source went on to say that Federline had created a “false dispute” as Spears has never opposed his plan to move their kids to Hawaii.
Federline gave his ex a deadline to approve his plan to relocate their sons to Hawaii. If she didn’t comply, he threatened to go to court to get a judge to sanction the relocation.
Federline’s lawyer, Mark Vincent Kaplan, revealed to TMZ that he had asked Spears’ lawyer Mathew Rosengart “several times” to send written consent stating that the Womanizer singer is “okay with the move” but had not received a response.
At the time, it was also claimed that Spears hadn’t seen her children in “more than a year”.
The pop star admitted last year that a “part of her had died” after not seeing her boys for six months. Her kids did not attend her wedding to Sam Asghari in June last year.
