If only living down past indiscretions were as easy as deleting your Twitter timeline.

Earlier this week, in an angry tweet aimed at those who continue to dwell on his 2009 physical altercation with then-girlfriend Rihanna, Chris Brown announced he was leaving the social-networking site.

His account is once again active, but only only a pair of tweets remains in his timeline. The latest, dated Nov. 15, reads, "Live LIFE!"

That seemingly positive message is a far cry from the rant he unleashed on Thursday (Nov. 17), when the R&B superstar blasted online haters.

"Don't say s--- to anybody and everyone feels its cool to attack me. GROWN ADULTS!!!!" Brown wrote. "That s--- happened three years ago. TWITTER GETS WACK REAL FAST! I LOVE ALL THE POEPLE WHO SUPPORT MY MUSIC! i never said i was a LEGEND. people please grow up. Ive never dealt with so much negativity in my life! its to the point now that its just ridiculous! IM NOT A POLITICIAN! MY MUSIC DOESNT PROMOTE VIOLENCE nor will it ever! only thing it will increase is the pregnacy rate!"

He followed that up with what appeared to be a reference to Rihanna, writing, "I know a lot of you wack a-s (OLD) celebrities probably wanna f--- my ex, but talking s--- on me wont get you far! and to be REALLY HONEST, ya'll wonder why n-a spazzes all the time?"

Brown added that he "can't wait" for the American Music Awards, which take place tonight in Los Angeles. The singer is up for Favorite Male Artist in the soul/R&B category, and he's also slated to perform.

"U dont have to respect me now... but u will," he tweeted.

The American Music Awards air tonight at 8PM EST on ABC.
