Kelly Clarkson predicted her first baby's gender even before she announced her pregnancy.

In this week's issue of Parade magazine, the Stronger singer said, "I'm totally gonna have a girl."

The American Idol season 1 winner predicted to the magazine, "I'm manifesting it! And when I have a girl, you're gonna be like, 'That chick knew it!'"

She also warned that her fans better not expect her to drop her pregnancy weight quickly after she gives birth next year.

"I've never been Gisele Bündchen, so ain't nobody expectin' that!" she said of the lithe Brazilian supermodel. "I like to set a [low] standard so people don't expect a lot."

Clarkson revealed her pregnancy with her first child with husband Brandon Blackstock on Nov. 19.

"I'm pregnant!!! Brandon and I are so excited!" she wrote. She then described the news as the "best early Christmas present ever."

She shared the news less than a week after telling Jay Leno on Tonight Show that she and her husband were "trying like rabbits" to get her pregnant.

"Practice makes perfect!" she told Leno. "We're trying, trying, trying."

She also announced their marriage on the social network last month.

"I'm officially Mrs. Blackstock :) We got married yesterday at Blackberry Farms in TN, the most beautiful place ever!" she tweeted on Oct. 21.

Blackstock is the son of famed music manager Narvel Blackstock, who manages Clarkson. His stepmother is country legend Reba McEntire.

Next month, Clarkson will also appear in her own Christmas special, which will follow her recently released first holiday album Wrapped In Red.

The television special will feature a long list of celebrities, including Robin Williams, Whoopi Goldberg, William Shatner, Danica Patrick, Heidi Klum and Jay Leno. There will also be a bevy of country stars, such as Blake Shelton, Reba McEntire and Trisha Yearwood, according to The Associated Press.
