Carrie Underwood's baby bump is definitely bringing her good luck as "Something in the Water" singer's album topped the Billboard chart.

The "American Idol" winner released her "Greatest Hits: Decade #1," which debuted at the top of the Billboard's Top Country Albums. The album has 25 of her most popular songs along with her latest track "Something in the Water."

According to Taste of Country, this is the fifth album released by Carrie Underwood that debuted at No. 1.

Sony executive Gary Overton credited Carrie Underwood for the "sheer depth and breadth of her music, whatever the subject matter, from the most nuanced performances to songs that just blow the roof off."

"With her Greatest Hits package debuting at No. 1, and 'Something in the Water' already a massive hit, it's an incredible testament to how profoundly Carrie's songs have connected with fans over the past ten years, as well as the awesome promise of the decades of music still to come."

"With all these records being broken and a new baby on the way, it may be safe to say that 2014 is turning out to be Underwood's best year yet," the website said.

With her baby bump, Carrie Underwood has been keeping herself healthy by being a vegetarian.

"I have been vegetarian for about ten years now. With pregnancy, I am definitely going more on the vegetarian side, but as soon as I am not pregnant anymore I will go back to being vegan," she told Yahoo Beauty. "I don't think I am craving anything too crazy. I try to keep it as healthy as possible and try to take care of myself. And, you know, putting good things in!"

Carrie Underwood's baby bump is not slowing down the "American Idol" winner as she hosted the CMA Awards, along with 11 costume changes, and attending several parties looking very blooming.
