It appears Amanda Bynes is doing everything she can to be the reigning queen of the gossip world. After getting arrested in New York on Thursday, the former Nickelodeon star publicly attacked pop princess Rihanna on Twitter Sunday afternoon.

Bynes blasted the “We Found Love Singer” for no apparent reason in a racist and offensive tirade. The 27-year-old Bynes, who refers to herself as a “retired” actress, accused Rihanna of “tryin to be white” and called her “ugly.” She soon deleted the nasty posts, but screenshots of the tweets taken by the Daily Mail and TMZ have preserved her attacks on the Barbadian beauty.

The outburst began with Bynes writing, “@rihanna you look so ugly tryin [sic] to be white.” A few minutes later, she slammed the singer for being assaulted by her on-again, off-again boyfriend Chris Brown. She claimed he assaulted her in 2009 for being unattractive: “Chris Brown beat you because you're not pretty enough.”

Next, the actress retweeted one of the 25-year-old singer’s posts: “Look who came to see me! My lover Stella McCartney!” About this, Bynes wrote, “No one wants to be your lover so you call everyone and their mother that I almost named my new dog Rihanna.”

Rihanna didn’t appear to take the tweets to heart. The singer, who is known for being feisty on Twitter, sent out a post after Bynes’ tirade that seemed to be directed at the former Nickelodeon star. “Ya see what happens when they cancel Intervention?” she wrote. Bynes, clearly unafraid of confrontation, fired back at 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! [sic]”

It’s not clear what sparked the fight, but it could have something to do with Bynes’ unrequited love for rapper Drake. She once tweeted she wanted him to “murder her vagina.” He also happens to be one of Rihanna’s ex-flames, which could have fueled the attack.
