NEW YORK: Justin Bieber is already being betrayed by his rumored new lady love, Chantel Jeffries.

A source tells New York Post gossip column Page Six that a rep for Jeffires reached out to the weekly magazines and to producers of shows including GMA, Today and Inside Edition to talk about her night with the teen star, which ended in his DUI arrest and infamous glassy-eyed mug shot.–SN
