Macklemore & Ryan Lewis' new album is full of collaborations, but one person won't be in the credits -- Adele.

The duo's sophomore record, This Unruly Mess I've Made, dropped Friday, and it features everyone from Leon Bridges to Chance the Rapper. Apparently, Macklemore (real name: Ben Haggerty) was hoping to get Adele to join the list of impressive names, but the dream never came to fruition.

The 32-year-old hip-hop artist told The New York Times that the "Hello" singer passed on joining on the song, "Growing Up." Ed Sheeran would end up on the final track.

"She graciously passed," Macklemore said.

Macklemore explained that Adele was the only artist who declined to work on the record, though "there were times that we never heard back from somebody's manager or something like that."

While plenty of artists are featured on Macklemore's latest release, even more names are mentioned within the tracks. Both Iggy Azalea and Miley Cyrus are called out for cultural appropriation on the song "White Privilege II."

When asked about the name drop by a fan, Azalea tweeted, "He shouldnt have spent the last 3 yrs having friendly convos and taking pictures together at events etc if those were his feelings."

That response would end up leading to a feud between the Australian rapper and hip-hop artist Talib Kweli. Get all the details on their heated exchange in the video below.
