Marissa Mayer is taking work-life balance to a whole other level.

According to the Wall Street Journal, the company's CEO slept through a dinner meeting last Tuesday with the Interpublic Group, a major advertising holding company. She admitted as much to some of the attendees, the WSJ reports.

Mayer had been set to speak with executives representing the likes of brewer MillerCoors and Greek yogurt maker Chobani at the dinner, which was arranged as part of the Cannes advertising festival.

But several attendees, including Interpublic Group CEO Michael Roth, ended up leaving before she got there, according to those familiar with the matter.

"It is another instance where she demonstrated that she doesn't understand the value of clients, ad revenue or agencies," one WSJ source said. Another anonymous source told Business Insider that Mayer had executives rearrange busy schedules so the dinner could be held at 8:30 p.m. sharp.

"We aren’t commenting on the story other than to say that we value our partnership with IPG and all of our advertisers," a Yahoo spokesperson wrote in an email to The Huffington Post.

Earlier in the week, spectators lit up Twitter during Mayer's presentation, calling it both overly scripted and unnecessarily promotional.
