Vanessa Williams and her husband, L.A. Laker forward Rick Fox, may have appeared to have been a happy couple, but according to a source close to Williams, the two have actually been quietly estranged for the last 18 months, PEOPLE reports in its upcoming issue.
Williams and Fox married in 1999 and have a 4-year-old daughter, Sasha. The split is "not entirely surprising, since they've spent their entire marriage living on opposite coasts," says the insider. (Williams lives in Westchester County, N.Y., while Fox works in Los Angeles.)
Reps for both confirm the breakup but say neither side has filed for divorce.
Meanwhile, in more promising celeb romance news, forget Aaron Carter: Hilary Duff appears to have Good Charlotte lead singer Joel Madden on her mind these days. Duff, 16, and Madden, 25, were spotted at restaurants and parties together in Toronto last weekend. A source says that the two arrived separately at the MuchMusic Video Awards but were soon seen kissing in the VIP lounge.
Reps for Duff and Madden say that they are "just friends."
