Los Angeles, California - Britney Spears' ex-husband Kevin Federline has doubled down on his previous claims that she's estranged from their two teenage sons.

K. Fed's extended 15 minutes of fame has landed him back in hot water with Britney stans.

On Wednesday, 60 Minutes Australia released a new teaser of the former backup dancer's upcoming interview with the outlet, which has already been slammed by fans of the princess of pop.

In the brief clip, Federline doubled down on his stance that Britney has a wrecked relationship with their teenage sons Jayden and Sean.

He further remarked that while he "still feels bad" about her recently terminated 13-year conservatorship, he also "couldn't get involved."

"The boys, the boys, the boys. I had to worry about them. I couldn't get involved," Federline stated in the clip.

Regarding the teens, the 44-year-old added that "they actually haven’t seen her in months," with the show's narrator adding that the move is "the boys' decision to snub their mother."

Meanwhile, the Toxic singer is seemingly unfazed by her baby daddy's allegations.

Britney dropped a new clip on Twitter Wednesday night showing off her new mermaid-like tresses, while Boyz II Men's Water Runs Dry played softly in the background.

"First time having really long hair !!!" the 40-year-old tweeted. "It’s different … serving evil mermaid vibes I guess except I have legs !!! Pss too hot to go outside bored as hell !!! Psss this is not a hair commercial !!!"

The singer also recently rejoined the music scene with a new track that and Elton John collaborated on. She also appears to be enjoying being newly married to Sam Ashgari.
