While watching the closing ceremony of the 2012 London Paralympic Games, Morgan wrote on Twitter: "ps I think @rihanna needs to grow her hair back. Fast"
Later, Rihanna hit back at Morgan, below the belt, telling the talk show host to grow a certain reproductive organ.
Rihanna tweeted: "@piersmorgan ps I think @rihanna needs to grow her hair back. Fast." grow a dick…. FAST!!!"
