Richie ensured she would leave her lover red-faced, by telling Osbourne she was "yummy," asking Abdul if Madden could "smell her armpits," and tweeting Parton to see if she had any "milk in those jugs."
Later, Richie also aimed her mischievous side at Kardashian, tweeting on the reality star's blog, "Sometimes I think I'm a lesbian because HOT DAMN Nicole Richie is fine."
Richie later revealed herself as the culprit by uploading a picture of herself grinning on the top of their Twitter pages.
