Rihanna told CNN host and general irritant Piers Morgan to 'Grow a di*k' during a Twitter row following the closing ceremony of the Paralympic Games last night (Sept 9).
The pair fell out after Morgan, watching the ceremony from home, remarked on Rihanna's performance with Coldplay and her new short hairstyle by saying: "Love them or hate them, #Coldplay are a proper stadium band. Thus, ten times better than 95% of other musical acts at Olympics/Paralympics."
Adding: "ps I think @Rihanna needs to grow her hair back. Fast."
Rihanna did not take well to fashion advice from the TV star and immediately fired back at him, quoting the original Tweet and adding: "grow a dick..... FAST!!!!"
The pair did, however, make up and semed to agree a deal for Rihanna to be a guest on Morgan's US chat show.
Rihanna had a busy night last night, having joined Coldplay on stage inside the Olympic Stadium for a huge performance of their hit single 'Princess of China'.
In perhaps the worst kept secret in the music industry, Chris Martin brought out guests Rihanna and Jay-Z as part of the show - performing 'Princess of China' with Rihanna and a special version of 'Paradise' with Jay-Z.
