Ray J is countersuing Kim Kardashian and Kris Jenner for breach of contract.

The 44-year-old singer - who was infamously Kim's partner in her 2007 sex tape - was sued for defamation by the pair last month after they accused him of waging a decades-long campaign against them with his repeated claims that they are the subject of a federal criminal investigation into racketeering.

And now Ray J has filed a response to their lawsuit by submitting a cross-complaint in which he alleged Kim, 45, and 70-year-old Kris had violated the provisions of a $6 million settlement agreement they reached in 2023 over the sex tape, TMZ reports.

Ray's legal team branded the allegations in The Kardashians stars' lawsuit a "public relations charade" filled with "malicious falsehoods" and insisted it is "not about defamation" but "about publicity, power and punishment."

The One Wish hitmaker alleged the pair have taken legal action "to feed their insatiable appetite for attention, garner support for their various media and marketing enterprises, and exact retribution.

The documents added: "They are furious that Norwood no longer wants to play along with their tall tale."

Ray has sought for their lawsuit to be dismissed and is also seeking $1 million in damages plus interest, legal fees and "further relief" that may be seen as "just and proper", arguing damage to his business prospects and the terms of the alleged agreement he had made with Kris and her daughter.

The Sexy Can I singer claimed in the lawsuit that he and Kim had consensually recorded their sex tape in 2003 and began discussing releasing it publicly in 2006, and alleged the All's Fair actress insisted her momager oversee its release.

He said the trio all signed licensing agreements with Vivid Entertainment, the adult entertainment company who released the video in 2007 but alleged "Kardashian, Jenner, and Vivid agreed that Kardashian would file a bogus lawsuit" claiming she didn't "intend, authorize or consent" to its distribution "to create buzz ahead of the tape's release."

Ray insisted the claims against Vivid "were lies" and accused the pair of leaking news of a fake $5 million settlement to TMZ.

The lawsuit added: "For the next two decades, Kardashian took every opportunity to draw attention to herself and painstakingly weave a false 'victim' narrative around the Sex Tape."

He further claimed the Skims founder and her mother "manufactured a fresh fake Sex Tape 'controversy'" to "generate publicity" for the premiere of their Hulu series The Kardashians in 2022.

The complaint alleged Kim said on the show that Ray had given their leaked sex tape to his "former manager" even though "she knows he never possessed" it and that he had "sexually assaulted" her while she slept.

And he claimed Kim, Kris, Kendall Jenner, and Kanye West - who was previously married to the reality star - had made statements on the programme which accused him of extorting them for a laptop supposedly containing another unreleased sex tape.

Ray alleged he had messaged Kim on Instagram at the time to "confront her" about the comments on the show.

The legal documents stated: "Kardashian begged him to go along with yet another false 'story' that she wanted to run on the show: that they were working with Vivid to remove the Sex Tape from the internet."

But he "declined" and subsequently sued Kris and Kim, reaching a settlement in April 2023 in which they and their production company allegedly agreed to pay him $6 million and pledged "that no further mention or public reference' to the sex tape is made on The Kardashians, and any further disparagement entitles Norwood to $1 million in liquidated damages."

However, Ray insisted the agreement was broken during the show's third season with comments on the show, just a month after the settlement was reached.

The reality stars allegedly then sought to modify the agreement to release them from liability for "'public statements' that 'were made but not publicised until after the Effective Date."

In their defamation lawsuit, Kim and Kris took action over comments Ray made on TMZ in May and on Twitch in September, but he argued he didn't know his "off-camera" remark on the latter was being life-streamed, while his words to the news outlet were just an "aside".

He insisted that if his statements "constitute a breach", they were not material and should be "excused" by Kim and Kris' alleged "material breaches".

Kim and Kris' legal team have branded the countersuit "frivolous".

Alex Spiro told People magazine: "After realising he is losing the case and losing his way, this disjointed rambling distraction is not intimidating anyone. Ray J will lose this frivolous case too."
