Michelle Williams had everyone talking this past weekend when she brought her Destiny’s Child sisters Kelly Rowland and Beyonce on stage with her as a surprise opening to the 2015 Stellar Awards.

Michelle who was nominated for multiple categories for the gospel award show, hit the stage to perform her hit ‘Say Yes’ which features the ladies, and performed the song for the first time with them on Saturday as the onlookers went wild.

Now following the big event, Michelle sat down with ‘ET’ to talk about the performance, how they kept it a secret, and more. We even get a small teaser of the performance which is set to air on TV One this Sunday. Check out the interview below.

Check out another ET interview she did immediately after the Stellars.
