All through Beyoncé Knowles’s lip-syncing controversy, the singer has remained silent though several stars such as Jennifer Lopez and Aretha Franklin came to her defense.

But now, the singer has taken to the photo sharing platform Instagram to react. The “Single Ladies” singer recently posted online a photo of herself wearing a sweatshirt that read, “Can I live?” a song by her husband Jay-Z.

While it is clear that Beyoncé has had enough of the controversy, her upcoming 2013 Super Bowl Halftime performance is sure to attract much media attention. There are many who predict that Beyoncé would once again lip-sync at the Super Bowl Halftime show, as it is difficult to sing and dance at the same time during a live performance.

“It’s very difficult to sing and dance at the same time,” Mike Stevens, vocal chair at The Colburn School in Los Angeles, told ABC News. “So I would not be surprised if she lip-syncs.”

Interestingly, Madonna’s performance at last year’s Super Bowl Halftime show was also lip-synced, though it went on to be a huge success. The pop queen later revealed that lip-syncing was one of the most nerve-wrecking experiences of her career.

Beyoncé got caught in the lip-syncing controversy when she chose not to sing live during President Barack Obama’s Inaugural function on Jan. 21. Her flawless rendition of the national anthem garnered rave reviews, but it later emerged that Beyoncé had lip-synced the whole performance.

Since then, many artists and industry experts have come to her defense saying that “The Star-Spangled Banner" is a difficult song to sing live.

“[It's] a song that spans about 1.5 octaves, and it kind of scares most singers to death just because of where it hits them in their voice," vocal coach Jan Smith told ABC News.

"It usually splits their voice in half, and singers are not, typically, as comfortable in the high end parts or crossing over into falsetto. So, it's kind of a tricky song for most people."
