Iggy Azalea was the latest star to join James Corden for carpool karaoke. They sang along to her biggest hits — “Fancy,” “Black Widow” and “Trouble” — before hitting a bridal store. Yep, that’s right. Corden tried to help Azalea pick out a wedding dress for her upcoming nuptials.

The trip wasn’t a total success, but Azalea revealed that Demi Lovato will be one of her bridesmaids. Oh, and that her fiancé Nick Young wants R. Kelly to perform at their wedding.
