Swift's unrestrained enthusiasm was on display as the Kansas City Chiefs faced the San Francisco 49ers.
Swift was shown cheering enthusiastically on the broadcast after one exciting play in the second quarter that appeared to be going well for boyfriend Travis Kelce's team.
Unfortunately, it did not last long, as the Chiefs quickly turned the ball over.
Swift appeared to be uncomfortably swaying during the first quarter while laser-focused on the game, which was still 0-0 at the time.
She also looked to relax when she was shown on the jumbotron chugging her drink, according to footage recorded from inside the stadium and put on X by the NFL's official account.
During the pre-show performances, Swift and Blake Lively were seen on CBS dancing back and forth to Post Malone's performance of "America the Beautiful."
Malone is a featured artist on Swift's new album, "The Tortured Poets Department," which is due out on April 19.
Earlier this week, McEntire spoke with PEOPLE about how excited she was to play "The Star-Spangled Banner."
"Oh, I'm quite excited. You understand, it's not about me. It's about everyone who worked so hard to get to the Super Bowl,
my duty is to convey the patriotism," the "Fancy" singer stated in a recent interview about her new collaboration with Sonic.
