Rihanna's Tweet about Justin Bieber's six-pack has become one of the most popular messages on Twitter in 2010.

The 'Loud' star Tweeted that Bieber had flashed her his stomach in November before asking his fans not to kill her.

Her Tweet, which read: Justin Bieber just flashed me his abs in the middle of a restaurant! Wow! He actually had a lil 6 pack! Sexy, lol! #Beliebersplzdontkillme was the ninth most re-tweeted message of the year by fellow Twitter users.

Elsewhere in the Top 10 Tweets were entries from rapper Lil Wayne ("Aaaaaaahhhhhhmmmmm baaaaakkkkkkkkkk!") at Number 3, Drake ("We always ignore the ones who adore us, and adore the ones who ignore us.") at Number 2 and Kanye West ("I'm sorry Taylor.") at Number 8.

Teen stars Justin Bieber and Joe Jonas proved popular with their messages hitting Numbers 4 and 6 respectively. Bieber's message of choice was "Te quiero mucho mi amor" which is impressive for someone who doesn't know what 'German' means.
