Report: Rielle Hunter Wants Paternity Test

As if Elizabeth Edwards' book tour - one seemingly designed only to humiliate John Edwards and Rielle Hunter - the former presidential candidate's furious mistress is demanding he submit to a DNA test, according to National Enquirer.

NOTE: Before discrediting this report based on the source, do recall that it was this very celebrity gossip tabloid that broke the story of his affair - and the possible love child that Rielle gave birth to in February 2008 - in the first place.

When Edwards finally came clean regarding the affair last August, he said the father was his former aide, Andrew Young, and Hunter declared that there would not be any paternity testing on her daughter, Frances Quinn. Quite convenient.

But now, the Enquirer says she wants proof that John Edwards is the father of her 14-month-old love child and is working with a lawyer to take legal action.

The blonde divorcee, 41, has been derided as pathetic in the new book, Resilience, written by the ex-senator's cancer-stricken wife, Elizabeth Edwards.

Rielle's sudden move to determine paternity is a clear signal that she is no longer willing to protect the philandering politician, according to sources. 

Having been thrown under the bus by Elizabeth Edwards in her new book, an enraged Rielle Hunter is apparently trying to take John Edwards down with her.

Edwards is also the subject of a federal investigation into the possible misuse of campaign funds in payments made to Hunter's "production company."

"Rielle - probably naively - now realizes she had held onto a false promise that if she continued to take part in the cover-up John had engineered, they'd be together in the future," a source close to Hunter told The Enquirer.

Of the likely fabrication that Andrew Young is the father, the source adds:

"[Rielle Hunter] was willing to protect John for the sake of the child. She agreed to allow a crony of his to claim publicly that he is the baby's father, and she even kept the name of the father blank on the birth certificate."

"But now she can see there's never going to be a future with John - and she feels he's lied about his promise to keep Elizabeth from trashing her in the book."

"Rielle is so infuriated by his and Elizabeth's actions that she's throwing her loyalty to him out of the window! Rielle wants the paternity of her daughter Frances finally established. She knows it could ruin John for good."

Ruin him how? Quashing a third presidential run?

Seems like he's pretty ruined as is, but why not pile it on? He's still probably lying about the child, after all, and we'd hate to see him get away with that. Seriously, who cheats on their cancer-stricken wife while running for president?

Think a small part of Elizabeth Edwards is loving this right now?
