Carrie Underwood melted hearts on the red carpet.

The "American Idol" alum was asked at the 2016 Grammys what she's most proud of in her life, and the 32-year old told E!'s Ryan Seacrest, "Being a mom."

She said about her son Isaiah Michael Fisher, whom she shares with husband Mike Fisher, "My little guy is the little sunshine in my world, every single day."

But he's still too young to make a red carpet debut!

Isaiah Michael turns 1 on Feb. 27.

"He's back at the hotel right now and he's just smiley and sweet and happy and just...he's the best," Carrie added.

On the red carpet, she stunned in a black strapless Nicolas Jebran gown.

She is set to perform during the awards show and is also nominated for Best Country Solo Performance for "Little Toy Guns."

Even though she's performed at the Grammys before, Carrie admitted that she's nervous.

"I'm glad I still get nervous because I feel if I'm nervous, it means I care," she said. "It's amazing, amazing company and I'm just excited."
