Rihanna To Piers Morgan: 'Grow A D-ck'

Rihanna and Piers Morgan got into a unique sort of argument on Sunday night -- one that played out, unsurprisingly, on Twitter.

Things started when Morgan, watching the pop star's performance at the closing ceremony of the Paralympic Games in London, tweeted that she needed to "grow her hair." Rihanna took note of this:
