Beyonce and her former bandmates have been coy about reports of a comeback at the Superdome in New Orleans, Louisiana, during the half-time show.
But it seems they haven't been able to lock down rehearsals.
Cheerleader Courtney Labat, who will be performing with Beyonce on Sunday, was caught out on Friday when Entertainment Tonight reporter Rocsi Diaz asked her if rehearsals with Michelle Williams and Kelly Rowland have been good.
She replied: "Yeah, they've been awesome. We were actually able to see the show yesterday."
If the reports are true, it will be Destiny's Child first public performance in five years.
