Sharon commented: "He says this stuff to get a reaction. I know Piers Morgan very, very well. This is what he does. He just throws things out there to get this reaction that he's getting.
"He loves the attention. Naughty Piers! I know you don’t believe what you're saying. He doesn't. He adores women."

But, fellow panellist Aisha Tyler disagreed with Sharon, saying he sounded "misogynistic".
The actress, 46, interjected: "I’m offended… I just don't think he understands American democracy and our constitutionally protected right to assemble and have free speech."
Aisha went on: "I think when he comes here, we'll explain how democracy works."

Their remarks come after Piers, 51, blasted Ewan, 45, in his Daily Mail column, calling him an "unprofessional, narrow-minded and anti-democratic twerp".
The Hollywood star had previously tweeted: "Was going on Good Morning Britain, didn't realise @piersmorgan was host. Won't go on with him after his comments about #WomensMarch."
Piers later stated: "Sorry to hear that @mcgregor_ewan – you should be big enough to allow people different political opinions. You're just an actor after all."
