I've become an even bigger fan of her's after the Dateline interview. She is an an incredibly talented and remarkable woman. She deserves every bit of success that has come her way. I was very sad when was voted off of 'Idol' in 2004, but was so thrilled for her when she won the Oscar, Golden Globe, BAFTA, SAG, and then she won a Grammy two years later.
It's the way the kids are conversatin' now. It's a contraction of "her is," as in, "I am an even bigger fan of her is..." as in "her being." See also, "her isness"; example: "Her isness is so total I schimply bow to her schtrength."
As long as we're going all in, let's just remind the people of youth that the suffix "ing" is not pronounced "een". I schtudied speech so I know what I'm talkeen about.
