Julia Fox slipped into a bubble bath for a sultry new ad to promote a mysterious new product from Kourtney Kardashian’s Lemme brand.

In a video released Thursday, Fox examined a purple bottle as she soaked in the warm water. Her blond hair was piled in loose curls atop her head.

She then rang up Kardashian, who was seen sitting on a luxe pink bed, wearing a pink fur-trimmed corseted bodysuit and matching opera gloves.

“Kourt…are you seducing me?” Fox purred into the vintage white phone.

“No, you’ll love it. It’s our new…,” Kardashian responded. However, the call was cut short before she could make the big reveal.

“Oops…guess we’re playing hard to get 😉💋✨” Kardashian and Lemme captioned the cheeky ad.

Fans in the comments section were prompt to note the uncomfortable link between Fox and the Kardashians — Fox was known to have dated Kanye West following his separation from Kim Kardashian.

“JULIA FOXX ?!?!” gushed a follower, while another quipped, “Ye meltdown in 3…2….”

“yasss the cross over i never knew i needed,” a comment read, while another stated, “getting back at Ye in the most professional but great marketing style.”

The former pair dated briefly in 2022, about a year after Kim initially filed for divorce from West in Feb. 2021.

“They’re kind of kindred spirits, and it’s cool to watch,” a source told Page Six of Fox and West in January 2022.

Even though their relationship ended after only a few months, Fox revealed in an interview with Entertainment Tonight that the brief affair was “the best thing that could have happened” to her during that period.

“It kind of brought a spark back into my life that I had kind of forgotten about,” she told the outlet in March 2022.

However, in January 2023, the “Uncut Gems” beauty started downplaying the relationship.

“We were literally together for like a minute,” said on an episode of “Watch What Happens Live with Andy Cohen.”

“I don’t think he even knows my full name or anything.”

In October 2023, she recalled an uneven relationship in her memoir “Down the Drain.”

Without explicitly naming West, Fox described it as a “sick, twisted game” for the “Stronger” rapper.

West, she wrote, dominated conversations while she “mostly” listened. She recalled only “occasionally chiming in. When he does listen to me, he loves my ideas and thinks I’m really smart.”

After his divorce from Kim was finalized in November 2022, the rapper famously married Bianca Censori.

Meanwhile, Fox became celibate after dating Ye, and came out as a lesbian in July 2024.
