Despite having divorced 16 years ago, Britney Spears is once again at loggerheads with ex-husband Kevin Federline after he publicly claimed their sons won't see her.
The interview saw KFed, 44 - also known as Meat Pole - claim that sons Sean Preston, 16, and Jayden, 15, have chosen not to see their mum for 'months on end' because of her racy Instagram pictures.
Britney, 40 - who pays retired backing dancer Kevin £16,400 a month in child support - hit back, saying she was 'saddened' that the father of her children had chosen to air their dirty laundry so publicly.
"I gave them everything," she wrote on Instagram.
"As we all know, raising teenage boys is never easy for anyone... It concerns me the reason is based on my Instagram. It was LONG before Instagram.

"One word: Hurtful... I'll say it... My mother told me 'you should GIVE them to their dad' ... I'm sharing this because I can!!!"
She also accused Kevin of exposing their sons to marijuana in his home, which led to Kevin sharing videos of Britney reprimanding her sons.
"As much as it hurts us, we decided as a family to post these videos the boys took when they were 11 & 12," he said. "This isn't even the worst of it. The lies have to stop.
"I hope our kids grow up to be better than this. #NeverFearTruth."
The drama comes eight months after Britney finally managed to escape a conservatorship that controlled her every action following her 2007 breakdown.
The controversial arrangement was put in place after Britney's mental health declined and saw her shave her head and attacking a paparazzo's car with an umbrella.
And her downwards spiral is all said to have started following her divorce from Kevin in 2006, when their son was just two months old.
Sources previously told The Mirror that the cracks formed while she was pregnant with Jayden, claiming that she had banished the would-be rapper to a self-contained 'bachelor' flat in the basement of their Californian mansion.
And Britney was the one to file for divorce, citing 'irreconcilable differences', amid reports of Kevin's partying - claims he has denied.
According to People magazine, the final straw came when Kevin headed off to Las Vegas to celebrate a nightclub's first birthday, leaving his wife - who had suffered from perinatal depression - alone to cope with two young children. He has always denied this.
A source claimed: "He said, 'I have to go to Vegas.' He didn't have to go to Vegas. He uses any excuse to party. She said, 'I've had enough.'"
"She tried to support him as much as she could, but at the end of the day she realised it wasn’t best for her and her children (to stay). She’s standing up for herself and making positive changes in her life."
However, Britney later alleged that Kevin had actually forced her to file for divorce, and even refused to see her while she was pregnant. This has also been denied.
In a since-deleted Instagram post, she wrote: "Geez my ex-husband wouldn't see me when I flew to New York with a baby inside me and Las Vegas when he was shooting a video!!!
"I got a text saying, 'If you don’t divorce Kevin he will publicly do it to you.' Since I hadn't seen him in a while I already knew it was over. I had my baby."
Kevin's attorney Mark Vincent Kaplan issued a vehement denial, insisting her version of events, "is completely the opposite of what's true, she knows that."
He continued: "She should be very careful about pursuing a dialogue that's based on revisionist history.
"That story about Kevin in Las Vegas and Britney is completely erroneous, and he's not going to stand by and let that story besmirch what he did and his support of her back in the day."
After several rehab stints, Britney lost custody to Kevin when she barricaded herself in the bathroom with her youngest son Jayden for three hours before being carried out on a stretcher and detained on a 14-day psychiatric hold for her own safety.
The courts appointed dad Jamie her conservator in a move that was expected to last one weekend but controversially remained in place until last November.
Jamie and a court-appointed lawyer took control of the star's health, finances and personal life - managing everything from her career and custody arrangements to her weekly allowance.
Heartbroken and with no-one around her to trust, she bought two baby blue parakeets and named them Sean and Jayden after her children.
"That's how sad she was. She just needed companionship," says Hollywood gossip journalist Janet Charlton.
