Lindsay Lohan was set to host the World Music Awards over the weekend until Samantha Ronson made her pull out (”pull out” . . . heh heh heh) because she was jealous of co-host Jesse Metcalfe. From Entertainmentwise:

The Mean Girls star – whose relationship with Sam has been rumoured to be on the rocks lately – was lined up to host the event with the Desperate Housewives star – until she mysteriously backed out. According to UK reports, Sam couldn’t bear the thought of her girl getting close to another man, prompting Lindsay to duck out of her hosting duties.
