SISTERS AT WAR!

KOURTNEY KARDASHIAN ACCUSES SISTER KIM OF A "GREEDY ACT OF TREACHERY" THAT NEARLY RUINED HER WEDDING AS THEIR BAD BLOOD CONTINUES.

KOURTNEY KARDASHIAN’S third wedding to Blink-182 drummer Travis Barker was a lavish affair. Sponsored by Italian fashion house Dolce & Gabbana, it took place May 22 at the designers’ luxe villa in Portofino, Italy. The seaside town is known for yachts, stunning views — and, for Kim Kardashian at least, wheeling and dealing. Turns out, the SKIMS founder, 42, spun a D&G collab worth a reported $15 million out of Kourtney’s big day. Or, as the 44-year-old deadpans in the season 3 trailer for the family’s Hulu show, The Kardashians, “My sister used my wedding as a business opportunity.”

And, as sis Khloé Kardashian puts it in the clip, Kourt is “livid.” She was blindsided, says an insider. “She’s saying the deal was a greedy act of treachery and way out of line.” Now sources tell Star, not since Kim and Kourtney’s infamous physical fight in 2017 have the two been so at odds with each other — and it’s not just for TV. “They can’t be together longer than five minutes without fighting,” says an insider. “It’s really toxic.”
