Meet Bunny Mellon, the 99-year-old heiress who helped fund Edwards' presidential run—and apparently his extra-marital exploits as well.

You'd assume Rachel Lowe Lambert Lloyd Mellon—who, just shy of 100 years old, is probably the last surviving member of the old-money aristocracy that once lorded it over America—would be mortified by her involvement in a tabloid-ready sex scandal.

Hardly.

According to confidantes of the reclusive high-society doyenne best known as "Bunny," she's predictably annoyed by the media glare, and was infuriated last week when an ABC News helicopter buzzed her mansion in the Virginia horse country to get aerial photos for Friday night's 20/20 segment based on a tawdry tell-all book by Andrew Young, a disgruntled ex-aide to her embattled friend John Edwards.
