Car conversation turned to Iggy's upcoming wedding to Nick Young, which she wants James Corden to officiate. They even shook on it so it's Carpool Karaoke official.
Iggy also revealed a famous face among her wedding party – pal Demi Lovato. So cool...we can't wait to see pics! Iggy explained, "[I'm going to have] four bridesmaids. Literally everyone I'm friends with. Demi Lovato's going to be one of my bridesmaids. She better sing at my wedding."
Of course, we're not sure if that was legit, given the fact that her hubby-to-be wants R. Kelly to perform "Marry the P***y" at the wedding too. Um.
James and Azalea even squeezed in a little wedding dress shopping and aren't they visions in white? They took their new gowns back to the car to continue singing I-G-G-Y hits. So fancy.
