Michelle Williams admits thinking about Destiny’s Child performing at the Super Bowl gives her a “headache”.

Speculation about the girl group making their live comeback at the NFL half-time show next month has been fuelled after a leaked set list surfaced. It is believed Beyoncé Knowles will be joined by Michelle and Kelly Rowland during her headlining spot on February 3.

Michelle is staying silent about the Super Bowl rumours, but admits she is finding her hectic schedule rather overwhelming.

"Unfortunately, I honestly can't say," she told MTV News when asked about the possibility of a Destiny’s Child Super Bowl performance. "Just thinking about it gives me a headache. It seems quite impossible because of our own individual schedules. My opening night for [theatre show] Fela! is January 29. I've been in rehearsals for that, so I haven't had time to think about learning anything else. But who knows? Maybe sometime in the future, five or ten years from now, we'll see."

According to Us Weekly, Beyoncé will be joined halfway through her set by Michelle and Kelly for a rendition of Survivor, Bills, Bills, Bills and their new single Nuclear.

Michelle revealed reuniting with her Destiny’s Child bandmates for their new compilation album Love Songs was great fun. She says they were surprised by how great they sounded together in the recording studio.

"It was a bunch of fun. It was just picking up right where we left off. Beyoncé laid hers first, then I'd go and lay another note to the bottom, and I'm like, 'Wow, this is dope,'” she explained. “I literally got goosebumps. [After hearing it,] Beyoncé sent an email like, 'Man, we sound good together!' I'm like, 'Duh, that's what we do, boo! That's what we do!'”
