Back in March, John Mayer briefly broke up with Katy Perry but he soon came to his senses and realized he couldn't be "alone."

Now back together with Perry, the "Paper Doll" singer put his thoughts in the song "Who You Love" in which he gave his girlfriend the opportunity to put down some vocals expressing her own romantic feelings, according to the Daily Mail.

Apparently Perry was satisfied with the results of the song, which is featured on Mayer's Paradise Valley album. The "Firework" singer took to Twitter on Monday to tweet her more than 40 million followers about the album's release.

She wrote, "Something VERY special is happening at midnight EST tonight on iTunes! My incredible, inspiring boyfriend John Mayer will release a spectacular record called Paradise Valley check it out here."

In an interview with Billboard, Mayer confessed that his desire for self-reliance has led him to feel isolated. He said, "I tried to be alone and I can't."

Mayer explained how the song shows explains how you cannot control who you love. He added, "It's also a confessional for myself. I started singing [the song], 'My girl, she ain't the one I saw coming and sometimes I don't know which way to go and I tried to run before, but I'm not running anymore.'"

He described what it was like to have Katy Perry on the song, "It's a really fun opportunity for her to write like her answer to that."

"So, you get these two sides to this relationship that are brutally honest."

Perry's lyrics responds to Mayer's thoughts as she sings, "My boy, he ain't the one that I saw coming. And some have said his heart's too hard to hold. And he takes a little time but you should see him when he shines."
