Jenny Lee Burton. I actually saw that episode and I don't usually watch Oprah.
She's got her own website too.

Adding:
"In her quest to get the "perfect face," Jenny decided she wanted Michael Jackson's nose. Although her plastic surgeon told her she could never have Michael Jackson's nose, Jenny insisted. She has had a total of three nose jobs and says, "The last time I went in there [the plastic surgeon] said to me, 'I'm warning you. If I do this, there's a very good possibility your nose will completely collapse and it will be flat on your face. And we will have to start all over again.' And I said, 'I'll roll the dice.'""(from Oprah.com)
You'd swear she was in her 40's-60's instead of 28.
