Iggy Azalea talked about her wedding plans with James Corden on "The Late Late Show" Thursday, June 16

The 25-year-old newly engaged rapper rode with Corden in his car on Thursday and dished out some of her preparation details, New York Daily News reports.

The "Fancy" rapper tried on wedding dresses, telling Corden that he could officiate her special day with basketball star Nick Young if he is ordained in time.

"Nick wants to have R Kelly perform at our wedding so he can sing 'Marry the P*ssy' with R Kelly,'" Azalea said. But Corden said he thinks Nick is going to go "straight up K-Ci and JoJo 'All My Life'" for the first dance.

"(I will have) four bridesmaids, literally everyone I'm friends with. Demi Lovato's going to be one of my bridesmaids, and she better sing at my wedding," Azalea said.

The rapper and Corden sang "Fancy" and "Black Widow" together, including other Iggy songs, throughout their car ride and then rode home wearing wedding dresses.

Corden said no one goes into planning a wedding thinking they would become a Bridezilla, but Azalea is sure that she will not turn into one.

The Australia native talked more about her wedding on "Today (Australia)," Entertainment Tonight noted.

"I think I'd like something very glamorous and big ... maybe a big, long train," she said.

"I think when you are a celebrity you get to -- fortunately -- go on red carpets so much and wear the sexy silhouette gown, so I've worn my fair share of those, but don't ever get to wear something big with the train. I might do the whole thing."

Iggy's fiancé popped the big question during his 30th birthday party in the hills of Malibu.

"It was like a nighttime carnival, so it was really romantic when he proposed," the 25-year-old rapper shared. "At the end he thanked everyone for coming, and then he got down on one knee and proposed to me. It was very sweet."

The rapper and Los Angeles Lakers basketball player are set to get married next summer.
