Amanda Bynes is a Twitter tour de force and she doesn't regret it at all. With a few 140-character posts, she's managed to transform herself from a former child star to one of the most hilarously fascinating personalities on the site. From not-so-subtle hints at a tryst with Kid Cudi to a quip about "magic mushrooms," Bynes, who turns 26 today, makes for an oddly entertaining follow on Twitter. Take a look at her weirdest tweets to see what we mean.
