Carrie Underwood

Ever wonder how Carrie Underwood records 18 weeks of 'Sunday Night Football,' plus the playoffs?

If you've been 'waiting all day' for the grand unveiling of Carrie Underwood's new 'Sunday Night Football' theme song, wait no longer.

Carrie Underwood will once again welcome football fans into Sunday Night Football coverage on NBC this season.

Underwood confirmed that she'll be back for her 13th season of 'Sunday Night Football' on NBC.

From Mariah Carey to Justin Bieber and more, at one point these stars abstained from, ahem, pleasures of the flesh.

She sang a stunning rendition of "America the Beautiful."

She rose above some big technical difficulties.

Dare we say this is a modest statement for a star of Underwood's stature? Especially for such an event.
