WEIRD AL'S BORN THIS WAY PARODY

Pretty good stuff, per usual, from Weird Al....

From TMZ.com.....it apparently got denied to officially release though--

Weird Al ripped into Gaga on his blog this morning -- claiming the egg-encased pop star strung him along for weeks while he tried to get her approval for his parody "Perform This Way" ... and ultimately rejected the proposal.

But sources extremely close to the singer tell us, "There must have been a misunderstanding because [Gaga] is in no way trying to block the release of the parody."

According to sources, "She's busy touring and hasn't heard the song yet. Her manager hasn't had a chance to play it for her yet" -- adding, "She's a huge Weird Al fan."

A bizarre situation -- because Al claims Gaga's manager is the one who denied him in the first place ... forcing him to release "Perform This Way" unofficially on YouTube.
