Yelawolf Explains Why Eminem Collab 'Best Friend' Was The 'Perfect Record' For Them

His album Love Story drops on Tuesday.

On his new album, Love Story, due out on Apr. 21, Yelawolf has only one feature: Eminem.

It makes sense that Em would appear on the album -- he executive produced the project, and Yela is signed to his Shady Records -- but why did the Alabama rapper decide to ask the Rap God to hop on "Best Friend" specifically?

"The song was already really strong, and I knew that I was touching on something that was serious -- or, to me, it was," Wolf explained to MTV News on Friday. "The melody in the song, it came together, and I just thought, If Marshall, if he gets on this and understands this concept, that it would be outta here. So I just crossed my fingers and sent it to him. Luckily, he understood it perfectly, and obviously killed it."

This isn't the first time the two have collabed -- we heard them together on Yela's last album, Radioactive, for instance. But that track, "Throw It Up," had a decidedly different vibe than "Best Friend." The song, which also features Gangsta Boo, showcases the two Shady MCs delivering frenetic verses packed with double-time flows.

"Best Friend," though, has a more ambient sonic tone, and features Yela not spitting the quick-tongued bars he shown capable of, but singing his verses and the hook. Em, though, still resorts to the rapid rhymes. It creates a contrast in their styles for this particular record.

"It's the perfect record for him and I for this album," he added. "Because its me standing my own ground creatively and where I'm at on it creatively, and Marshall being Marshall. To not rap -- I thought it created a really cool vibe, and no one's heard us like that musically, and content-wise no one's heard that, either."

They've also already worked on the video, which Yela promises will be a treat.

"This video is the most cinematic video I've ever shot," he said. "It was myself, Marshall, and a wolf -- two humans and a wolf [are] the only people you see in this entire video."

Yela's Love Story hits stores on Tuesday.
