MUMBAI: British television personality Sharon Osbourne, who got into a heated discussion about her friend Piers Morgan with "The Talk" host Sheryl Underwood, says she didn't sign any gagging order and is all set to write a tell-all book about what happened.

A huge uproar ensued after Osbourne expressed support for Morgan on the show, when the latter was heavily trolled for criticising Meghan Markle for her opinions about English royalty on Oprah Winfrey's show recently.
