Justine Sacco - the now-former Communications Director for IAC, a company owned by Barry Diller - was about to board a 12-hour flight from London to Cape Town when she Tweeted: 'Going to Africa. Hope I don't get AIDS. Just Kidding. I'm White!'
The post had been retweeted over 3,000 times and was picked up by media outlets around the world, however Sacco remained completely unaware of it all because she was in the air.
The blonde publicist was pictured arriving in Cape Town looking shocked and talking on her phone.
Moments later the offending Tweet and Sacco's Twitter account disappeared.
A spokeswoman for the company has now confirmed Sacco has indeed been sacked.
