Did AMANDA BYNES come out of her showbiz "retirement" to start BEEF with JAY-Z and BEYONCE? 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.

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, quote, "So turns out I prefer chocolate over vanilla. Interesting."
