Who're you gonna believe, me or your lying obligate paternal allele? John Edwards once said it's "not possible" that he's the father of Rielle Hunter's daughter, but the National Enquirer reports a DNA test has proven he's indeed the father.

In a "BOMBSHELL WORLD EXCLUSIVE!", the Enquirer says Edwards took a secret DNA test at Hunter's request:

"Rielle had no choice but to demand John take a DNA test," said the close friend.

"She was worried about getting long-term financial support for her daughter. So she hired an attorney, and John consented to undergo a secret swab test to establish paternity.

"There was no surprise: The results of the DNA test proved John was Frances' daddy."

Another source confirmed to The ENQUIRER: "John always knew he was the father of Rielle's baby.

In an ABC News interview last year admitting his affair with Hunter, Edwards had this to say about the paternity issue:

"I would welcome participating in a paternity test. Be happy to participate in one. I know that it's not possible that this child could be mine because of the timing of events, so I know it's not possible. Happy to take a paternity test, and would love to see it happen."

We're sure he absolutely loved taking that test secretly and then reading about it in the pages of the Enquirer, which has been 100% right about everything on this story.
