Britney SpearsandKevin Federlineare speaking out amid a report that the singer is on drugs.

Over the weekend,The Daily Mailreported that it spoke with Federline, 45, about his concerns that Spears, 41, is using drugs. “I fear she’s on meth — I’ve been praying someone would make it public and that she wakes up. … It’s terrifying. She is the mother of my boys,” journalist Daphne Barak alleged Federline told her.

Now, in astatement posted on his Instagram Story, Federline wrote in part that the reporting is “false” and “repulsive” and said it “saddens” his family, which includes the two sons he shares with Spears — Sean Preston, 17, and Jayden James, 16.

“[The] lies and attempts to exploit minors is click bait and another repulsive example of where, unfortunately, certain journalism has sunk today,” he added, in part.

Spears also responded to the report with apost shared on her Instagram feed, in which she addressed her two sons and their strained relationship.

“The fact that people are claiming things that are not true is so sad … This may not even be them saying such things because it doesn’t make any sense to me for them to be saying that,” she said, in part. “… It makes me sad because I tried so hard to make things nice for you and it was never good enough. So you guys go behind my back and talk about me … it breaks my heart and the news is so low.”

“Hopefully it is just the news being hateful and Kevin nor Preston said any of those things,” she added.

“The Daily Mail, through Daphne Barak, posted a story yesterday containing numerous false and defamatory fabrications concerning my client Britney Spears that are attributed to Kevin Federline and his children, in particular regarding ‘crystal meth,' ” the letter begins.

Noting that Federline “acknowledged the falsity of Ms. Barak’s story” when he spoke to TMZ earlier in the day, Rosengart’s letter continues, “I have separately learnt that on several occasions, Ms. Barak sought to contact Britney under false pretenses, again using her minor children, which is exploitative, harassing, and outrageous.”

“And moreover, Britney’s representatives were never contacted prior to the publication of the story, further demonstrating actual malice and reckless disregard for the truth," the legal document added.

Rosengart also said he would “follow up separately” but asked the outlet to “please confirm” that it would “immediately delete and retract that false and defamatory story and conduct an internal investigation regarding this matter and the abuse of Britney and her children."
