In 2014, Uber CEO Travis Kalanick, his then girlfriend Gabi Holzwarth, and five Uber employees visited an escort-karaoke bar in Seoul — an outing that prompted a complaint to HR from an Uber female marketing executive who was a member of the party, The Information's Amir Efrati reports.

According to the report, women working at the bar wore numbered tags and sat in a circle, so that men — including one of Uber's "A Team" executives Emil Michael — could identify their favorites.

"Four male Uber managers picked women out of the group, calling out their numbers, and sat with them," the report said. The female Uber executive left, appearing "visibly upset," after the group headed downstairs to sing karaoke, The Information reports.

The recount is an especially bad look for Uber, which has come under fire in recent weeks for having a reckless culture.

The world's most valuable startup has been rocked in recent months by high-profile allegations of sexual harassment, some of which were outlined in a bombshell report from The New York Times about the company's internal culture.

In February, the company hired former US attorney general Eric Holder and his partner at his Covington & Burling law firm, Tammy Albarran, to conduct a review of the claims.

A representative at Uber sent this statement to Business Insider:

"This all happened about three years ago and was previously reported to human resources. In early March it was referred to Eric Holder and Tammy Albarran as part of their review."
