A clip of Sharon Osbourne in a heated argument with co-host Sheryl Underwood on The Talk went viral. Underwood asked Osbourne questions regarding her vocal support for Piers Morgan. Before asking the questions, Underwood clarified that Osbourne has always been someone willing to learn, so it seemed like an attempt for Osbourne to explain herself. But Osbourne was simply not having it. She lashed out and yelled at Underwood multiple times 'Well what!'
Osbourne has since issued an apology on Twitter.
In the meantime, a story about Sharon Osbourne firing an assistant went viral. Osbourne forced her assistant to go inside her house while it's on fire to rescue her paintings and dogs. The assistant did, and Osbourne still ended up firing him after removing his oxygen mask to put it on her dog.
