It's widely known that ghostwriting in rap exists, but it's something that's rarely talked about. After all, the nature of the arrangement is that the pen behind the face on the mic is meant to remain anonymous. But we may have just gotten a glimpse into who's responsible for one of the biggest hits of the last year.

Since her breakout in 2014, Iggy Azalea has faced accusations that she uses ghostwriters for her songs. During her BET Awards acceptance speech, Nicki Minaj emphasized that she writes her own lyrics -- which many took as a slight at Iggy, though Nicki stressed that wasn't the case. T.I. was even asked about it directly, and denied that he had any part in writing her words.

But Skeme isn't quite as absolute.

During an interview on Shade 45's "Sway in the Morning" radio show, the Inglewood, California rapper hinted at the fact that he played a role in writing "Fancy."

Things started off when MTV's own Sway Calloway told Skeme that he had heard he wrote a song, by a female artist, that became one of the biggest radio hits of 2014.

"Maybe," Skeme said with a smile.

At that point, Sway decided to get direct: "I heard you wrote 'Fancy.'"

"Yeah, we had something to do with it; a lot of push," the 26-year-old MC said. "We put trust funds up for that song. So, shoutout to that song."

He said, though, that he didn't write the hook, which is sung by Charli XCX. "That's that part I didn't have nothing to do with," he clarified.

"Fancy" isn't the first collaborative effort from Skeme and Iggy. In 2013, Skeme featured her on "High Levels," off of his Ingleworld mixtape.

Now, he's getting ready to drop the follow up, Ingleworld 2, hosted by DJ Drama, which drops on Apr. 28.
