Fashion’s biggest legal feud has ended.

Net-a-Porter founder Natalie Massenet has withdrawn a bombshell lawsuit against her ex-partner Erik Torstensson that shocked the fashion world.

Reps for the duo exclusively told Page Six in a statement: “The parties are pleased that all of the unfortunate litigation between them has been withdrawn.”

The exes have withdrawn all legal proceedings between them, which included the civil suit in California and a New York family law proceeding, we hear.

According to court filings, the Los Angeles suit has been voluntarily dismissed, sources further said.

In the now withdrawn California suit — filed in Los Angeles County Superior Court last month — Massenet reportedly alleged her discovery of Torstensson’s drug addiction and infidelity led to the couple’s split in May of this year.

The Post reported that Massenet, 60, alleged in the court papers, that her ex, “seduced Massenet and schemed to pursue a romantic relationship in addition to their professional one,” using her to “bolster his professional career.”

It claimed she poured over $95 million into funding Torstensson’s lifestyle to support his business ventures over the years while he was hiring prostitutes, abusing drugs like cocaine and ecstasy, and cheating on her.

Massenet also alleged that Torstensson reneged on promises to repay her, and she was previously suing for numerous claims including fraud, breach of contract and causing her “severe emotional distress.”

No further details have been released about the suit being withdrawn and why the exes reached a detente so far.

They were known as one of fashion’s foremost couples. “If Erik Torstensson and Dame Natalie Massenet host a house party, you must do anything you can to nab an invitation,” Tatler magazine once crowed.

Massenet, a former journalist, launched Net-a-Porter in 2000, and later became co-founder of venture capital firm Imaginary Ventures.

The Post reported that around 2009, Massenet — who was once married to French financier Arnaud Massenet — met Torstensson, who was running a marketing agency.

He pitched Massenet the extension of her fashion site Net-a-Porter for men, but by late 2010 their relationship had turned romantic, per the now withdrawn complaint.

Massenet sold her majority stake in Net-a-Porter for an estimated $76 million and remained on as executive chairman.

In 2011, she announced that she’d split from her first husband, and Massenet and Torstensson soon became fashion’s first couple, hanging with supermodels and designers.

Torstensson later launched the denim line Frame in 2012.

They had a child together via surrogate in 2017, and Massenet has two daughters from her previous marriage.

According to the LA suit, Torstensson was a big spender, chartering jets and buying art, and the suit said he broke up with the fashion founder in 2024 in a “shocking and traumatic” twist, per court docs.

The suit alleged that Torstensson, 47, checked into a treatment center, and Massenet allegedly found one of his old phones that contained “indisputable evidence, including explicit texts and photographs, that Torstensson had maintained multiple affairs with several younger women for years,” per the complaint.

An insider previously told The Post: Massenet is “not a foolish woman,” the fashion insider added. “But she was a woman in love that thought they’d be together forever.”

But it seems the exes have now buried the hatchet.

Neither commented beyond the joint statement.
