So much for taking Adele's advice about having babies.

After revealing to Jay Leno that she and her new husband, Brandon Blackstock, are "trying, trying, trying... like rabbits!" to get pregnant, Kelly Clarkson is finally expecting.

“I’m pregnant!!! Brandon and I are so excited! Best early Christmas present ever,” the 31 year-old confirmed on her Twitter.

The pregnancy is the first for the former American Idol winner, who wed her husband last month. Blackstock has two children from his previous marriage - Savannah, 12, and Seth, 6. “My kids love her. I couldn’t ask for a better stepmother for my children," Blackstock's ex-wife Melissa said of Clarkson.
