Just when you think Maren Morris has had her best year yet, she starts another ascent. The country singer's cross-genre collab with deejay Zedd, "The Middle," has moved into the No. 1 spot on the Billboard Mainstream Top 40 chart this week.

Morris and electronic duo Grey are collaborators on the song, which is No. 6 on Billboard's Hot 100 chart and No. 8 on the Hot AC Radio chart. "The Middle" has amassed more than 300 million streams since its release around the Grammy Awards earlier this year.

"I connected really heavily with the lyrics," Morris says of working on "The Middle." "Being a songwriter, I could really appreciate that. I loved the range and how much vocal exercising I got to do." She acknowledges what a huge opportunity it was for her, both to work with Zedd and to have the music video air during the Grammys.

"The Grammys, it's an iconic awards show, it's all-genre," she marvels. "Me, Zedd and Grey, we wouldn't be likely collaborators since I'm from country, but it actually works so well and the Grammys is what that's all about. I think it's actually very appropriate."

"The Middle" marks Morris' third chart topper. She garnered her first No. 1 hit with Thomas Rhett as a duet partner on his song "Craving You" and earlier this year hit No. 1 with her single, "I Could Use A Love Song" featured on her debut major label release, Hero.

Morris married Ryan Hurd in Nashville on March 24 and is currently relaxing and enjoying her honeymoon in Bora Bora.
