Rihanna all praise for Justin Bieber’s ‘sexy’ abs

London: Teen star Justin Bieber apparently ‘flashed his abs’ at Rihanna in the middle of a restaurant.

And the Umbrella hitmaker admits she was impressed with what she saw.

"Justin Bieber just flashed me his abs in the middle of a restaurant! Wow! He actually had a lil`` 6 pack! Sexy,lol!" a news daily quoted her as tweeting.

Realising her boast and the use of the word "sexy" could trigger outrage among several million Bieberettes, she later posted a link to ""#Beliebersplzdontkillme" - which roughly translates to ``believers in Bieber, please don’t kill me``.

Justin reassuringly responded: "@rihanna never that. It’s always love."
