Iggy Azalea is already in full-on wedding mode.

The rapper joined James Corden for the popular "Late Late Show" segment "Carpool Karaoke," and in between singing along to her biggest hits, the two went wedding dress shopping together.

Iggy showed off her singing voice as she and James traded verses on "Fancy," "Black Widow" and "Trouble" and talked about her upcoming nuptials to LA Lakers player, Nick Young.

Iggy, who promised she's not going to turn into a bridezilla, revealed that she will be having four bridesmaids in her wedding party -- and one of them is a pretty famous friend.

"[I have] four bridesmaids, literally everyone I'm friends with," she said. "Demi Lovato is going to be one of my bridesmaids and she better sing at my wedding."

As you may remember, Demi was in attendance when Nick popped the question to Iggy earlier this month.

But if Demi is just looking for a little fun at the wedding, then Nick, otherwise known as Swaggy P, has someone else in mind that can take the stage and perform.

"First dance I don't know, but I know Nick really wants to have R. Kelly perform at our wedding so he can sing 'Marry the P---y,'" she said.

If that doesn't say love, I don't know what does.

After the wedding talk, Iggy and James made their way over to a dress shop to try on some gowns, and I have to say, Iggy is going to make for one gorgeous bride.
