Troubled former actress Amanda Bynes continues to make headlines, following her arrest for throwing a bong out a window of her Manhattan apartment late last week.
According to TMZ, Bynes lashed out at singer Rihanna on Twitter Monday morning, unleashing a series of angry tweets before later deleting them.
"Chris Brown beat you because you're not pretty enough," she tweeted. "No one wants to be your lover so you call everyone and their mother."
Rihanna responded, taking a shot of her own at the troubled starlet.
Ya see what happens when they cancel Intervention?— Rihanna (@rihanna) May 26, 2013
Bynes responded with another jab, before quickly deleting the tweet.
"@rihanna unlike ur fugly faced self I don't do drugs! U need the intervention dog! I met ur ugly face in person! U aren't pretty u know it!"
It's unclear what exactly provoked Bynes to attack Rihanna.
