Christina Aguilera

Christina Aguilera's estranged father has confirmed the pop star is pregnant with her first child.

The "Fighter" singer has yet to talk publicly about reports that she's with child and her representatives are refusing to deny the news, but proud grandfather-to-be Fausto Aguilera is all smiles.

He tells Life & Style magazine, "I'm so excited. I want Christina to achieve all her goals. I wish her all the happiness in the world."

And insiders claim the pregnancy is not a big surprise for the 26-year-old singer and husband Jordan Bratman.

One source says, "She's thrilled. She's feeling wonderful and taking good care of herself. She's been planning this for a while, so her health is better than it's ever been.

"Christina's seen women with great careers, like Gwen Stefani, also raise great kids, and she feels as if she can follow their example."
