A Russian sugar daddy has confessed to the murder of an Instagram influencer whose body was found stuffed in a suitcase, officials said.

Maxim Gareyev admitted to authorities that he stabbed his love interest, 24-year-old Ekaterina Karaglanova, last week in Moscow after she “repeatedly insulted and humiliated” him, BBC reported.

Gareyev — who claimed he gave Karaglanova money on dates — said he lashed out because she told him that he wasn’t attractive, according to authorities.

“She told me that I was ugly and that even plastic [surgery] would not help me,” Gareyev reportedly said. “I could not stand it.”

Karaglanova — who boasted more than 87,000 Instagram followers — was discovered Friday, days before her 25th birthday, in her apartment with her neck slashed, according to BBC.

Following the slaughter, Gareyev claimed that he stripped her naked and stuffed her body inside a large suitcase, Moscow newspaper Moskovsky Komsomolets reported.

Gareyev appeared Thursday in court, where he apologized to her parents and told reporters that he was “ashamed of myself.”
