Embarrassing details of shamed senator John Edwards’ personal life came pouring out in court on Tuesday when his former aide took the stand to testify on behalf of the prosecution in his campaign finance violation trial.

After helping Edwards cover up his mistress’ illegitimate pregnancy during his 2008 presidential bid, Andrew Young has switched sides and testified Tuesday that Edwards called Rielle Hunter a “crazy s**t,” and said there was only “a 1-in-3 chance” that the baby was his, reported Charlotte.cbslocal.com.

As Breaking Celebrity News previously reported, the 58-year-old is accused of illegally channeling almost $1 million in campaign contributions to cover up the affair. Edwards has pleaded not guilty to the six counts he's accused of: four counts of illegal campaign contributions, one count of conspiracy and one count of false statements.

Taking the stand in the the Greensboro, North Carolina courtroom for the second day, Young told jurors that Edwards directed him to start giving money to Hunter in May 2007 after she threatened to go to the media and expose the affair.

Young claimed that Edwards then suggested asking elderly heiress Rachel “Bunny” Mellon for a donation for a “non-campaign” expense, and the strong supporter offered $1.2 million. Under federal law, donors are limited to giving a maximum of $2,300 per election cy
