Piers Morgan of CNN got wind of it when she performed during the closing ceremony of the Paralympics Games in London over the weekend, and he wasn’t a fan. The journalist tweeted that Rihanna needed to “grow her hair back. Fast.”

Within minutes of coming off-stage, Riri had fired back, telling Morgan, “Grow a dick…FAST!!”

Unperturbed, Piers asked, “This a good time to ask for an interview?” to which Rihanna surprisingly replied, “Haaaa! Only if it’s not about cosmetics! But phuck yea lets do it!!!!!!!!!”

Ahead of her appearance at the closing ceremony in London, Rihanna’s new stomach tattoo (shown below) had also become a trending topic on Twitter after she sent the pic to her 25 million followers. The latest inking – featuring the Egyptian goddess Isis – honors Rihanna’s grandmother Dolly, who passed away in July after a lengthy battle with cancer.

“Goddess Isis- Complete Woman – Model for future generations – GRANGRANDOLLY – always in and on my heart”, she told followers.
