MONTREAL (November 11, 2009)—Canadian pop star Celine Dion isn't pregnant after all, a publicist says.

Dion's U.S.-based publicist, Kim Jakwerth, said Wednesday the couple's doctor had initially confirmed a pregnancy in August through in vitro fertilization.

When that information started to leak to the public, Dion confirmed it, but a day later, she found out the embryo had not been implanted successfully.

Jakwerth says Dion did not immediately announce that she wasn't pregnant because she was hopeful another implantation would work, and had wanted to keep the matter private.

Jakwerth says the couple is going to keep trying.

Dion, 41, and Rene Angelil, 67, have an 8-year-old son Rene-Charles who was conceived through in vitro fertilization.
