Rihanna's latest promotional stop for Battleship is Tokyo, and lucky for us, the R&B starlet has been tweeting tons of updates from the road.

Of course, that's not the only thing she's been sharing with the world. Yesterday she wrote, "If u love something let it go...if it doesn't come back, hunt it down and kill it." Hmm, wonder who she could possibly be referring to?

In other RiRi news, we're curious to see if she's going to respond to Clay Aiken's recent comments slamming her singing abilities. During an appearance on Bravo's Watch What Happens Live, Clay was asked which current pop star wouldn't make it past the first round of American Idol and he replied, "Oh god there are too many, too many … I've stopped listing to them because they can't sing. Rihanna has some pitch problems for sure … and now I'm gonna get in trouble."

We predict a Twitter smackdown in 3...2...
