Destiny's Child star Michelle Williams has revealed rumours of the band reuniting at the Super Bowl in February are giving her a "headache".

The superstar girl group - also comprising Beyoncé Knowles and Kelly Rowland - are rumoured to be making their live comeback next month at the hotly-anticipated NFL half-time show.

Beyoncé is headlining at the coveted event on February 3 and some sources have suggested Williams and Rowland will be joining her on stage to mark their return to the charts.

Williams has played down the talked-about event to MTV News, explaining: "Unfortunately, I honestly can't say. Just thinking about it gives me a headache. It seems quite impossible because of our own individual schedules. My opening night for 'Fela!' is January 29. I've been in rehearsals for that, so I haven't had time to think about learning anything else."

According to reports, the superstar's will reunite on stage to perform 'Survivor', 'Bills, Bills, Bills' and new single 'Nuclear.'

Destiny's Child's new release, entitled 'Love Songs', is due for release on January 29 and is the band's first album since 2004's 'Destiny Fulfilled.'
