1:06 PM PT -- Sam is still going off about K-Fed's interview and Britney's relationship with her kids, saying, in part, "Eventually if not already they will realize their mothers choices are harmless and an expression of newly found freedom. There is nothing to be emberassed about just lots of things to be proud of."
K-Fed's lawyer, Mark Vincent Kaplan, responded to Britney and new husband Sam Asghari's weekend attack on Kevin, telling a photog outside Craig's in WeHo Sam doesn't know what the hell he's talking about.
Brit's boys supporting Jamie creates an interesting family dynamic here ... there's clearly a wall between them and their mom ... and Kaplan makes it sound like the boys will see Jamie before they see Britney, despite a restraining order against grandpa.
Remember ... Kevin ignited the back-and-forth when he did a recent interview with DailyMail, a portion of which was posted Saturday, where he claimed Britney's kids haven't seen their mom in months, skipped her wedding to Sam and are put off by her partially nude social media posts.
Britney and Sam fired a return salvo, ripping K-Fed for talking about her relationship with her kids in public and claiming he's out of work and living off child support payments.
Kevin's attorney took issue with Britney and Sam's coordinated attack ... he claims K-Fed and his wife Victoria work 24/7 to keep Sean and Jayden out of the limelight and says there's no negative words against Britney or Sam in Kevin's household.
