Did AMANDA BYNES come out of her showbiz "retirement" to start BEEF with JAY-Z and BEYONCÉ?  Or was her Twitter HACKED?

Because a picture of Jay recently popped up on her feed, along with the caption "Ugly Face".  She took it down, but obviously, a screen cap is all over the web.  (And you can see it here.)  (E! Online)

As you may recall, Amanda played Penny Pingleton, the girl who develops a serious case of JUNGLE FEVER, in the 2007 movie version of "Hairspray".  And life obviously imitated art, because in 2010, she Tweeted, "So turns out I prefer chocolate over vanilla.  Interesting."
