“American Idol” winner Carrie Underwood recently posted a hilarious photo of her son, Isaiah Michael Fisher, wearing an adorable ensemble.

On her Instagram account, Underwood poked fun at her son's fashion statement when she shared a photo of baby Isaiah at their home wearing a fedora without his pants on. She then gushed about the “mom life” that she’s currently living.

Fans of Underwood couldn’t help but laugh along with her following her post. Some fans were reminded of their own children when they were much younger. Other fans noted how adorable Isaiah is and how good of a job Underwood is doing raising him.

A few weeks back, Underwood also shared a photo of Isaiah having a blast outdoors. The doting mom revealed that her son loves the sun just as much as she does.

Meanwhile, NBC just dropped a 15-second teaser for “Sunday Night Football.” The video featured Underwood singing the new theme song, “Oh, Sunday Night.” In the clip, the “Jesus, Take the Wheel” singer could be seen wearing a golden sequined dress, standing and singing in an empty room, while some snippets from past football games were shown in the teaser.

According to Billboard, “Oh, Sunday Night” is a re-work of Underwood and Miranda Lambert’s 2014 duet “Somethin’ Bad.” The song was part of Lambert’s “Platinum” album that peaked at No. 19 on the Hot 100 list and ranked No. 1 on the Hot Country Songs chart.

“Sunday Night Football” will kick off on Sept. 11 with a game between the New England Patriots and Arizona Cardinals. It will also serve as the much-awaited rematch of Super Bowl 50.
