It seems like it. On Feb. 6, the 26-year-old tweeted a photo of the rapper and wrote "Ugly face." Bynes has since deleted the tweet which was aimed at a Twitter user who doesn't appear to be active or connected to her.
While it's possible that Bynes' account was hacked, it's also very possible that she posted it herself. The actress has been exhibiting strange behavior since 2011, and it's only become more pronounced in recent months.
Bynes has a habit of tweeting and deleting, and even recently deleted a Tumblr account she started less than a month ago. The former child star appears to have been busy deleting her tweets, since there's only 13 left, but we should note that her Instagram account, where she posted a photo of her boobs last month, is still alive and going strong.
