Found the article. It's from the Guardian, which is a respectable paper.
Here's the important bit, but the whole article is quite good.
In 1991, Rose had fallen madly in love with Seymour and had become extremely attached to her three-year old son Dylan, but in 1993 Seymour abruptly left Rose to marry multi-millionaire businessman Peter Brandt. According to his few current confidantes, Rose is still hopelessly smitten with Seymour: the new age psychics whom he has employed continuously over the past 12 years claim she is his eternal soulmate and that they have been together in past lives.
And in the only print interview he has given over the past 10 years, with Rolling Stone in early 2000, he stressed that the lyrics to most of Chinese Democracy, the never-ending forthcoming Guns N'Roses album, will tell his side of the Seymour affair. "I hope [Seymour's son Dylan] hears it when he grows up, if he ever wants to know the whole truth."
Dylan Seymour is already a teenager, but he's going to have to wait a while before he hears his Uncle Axl's new lyrics. A decade after it was first begun, Chinese Democracy remains unfinished. More than $10m of studio costs, more than eight separate producers, more than 20 musicians involved in endless sessions - and still the wait goes on.
