Ciara's National Anthem at the College Football Championship Didn't Impress the Internet, But Russell Wilson L

The singer took some heat on Twitter for her shimmer gown/cape combo and vocal styling, but she still felt the love from her adoring boyfriend.

It seems not everyone loves Ciara as much as her boyfriend, Seattle Seahawks quarterback Russell Wilson.

The 30-year-old singer performed the national anthem at the start of the College Football Playoff national championship between the Clemson Tigers and the Alabama Crimson Tide in Glendale, Arizona on Monday, and while some — including Russell — appreciated the performance, others were a bit more critical.

Her loving, 27-year-old boyfriend was quick to show his support, tweeting that Ciara "sounded amazing & looked flawless in every way!"

However others were not as impressed. Taking the singer to task for everything from her vocal stylings to her long, cleavage-baring white gown with its flowing cape, some commenters on Twitter weren't exactly into the "I Bet" singer's performance.

Some said her sparking gown made it look like she was "heading to prom" after her big number, while others drew comparisons to Game of Thrones, calling the dress Ciara's "Khaleesi costume."

Many others took up the torch for the singer, praising her voice, her "beautiful" outfit and her "classy" delivery of "The Star-Spangled Banner."

Ciara got a lot more love for her rendition of the national anthem when she performed at the MLB All-Star Game back in July, where she rocked a much sportier ensemble and managed to avoid all the pitfalls the iconic song can present for singers.

Wilson shared his love and support for his girlfriend's talent after that performance as well. For more on the super cute celebrity couple, check out the video below.
