Justin Bieber's new song features head-turning lyrics about wife Hailey Bieber

Justin Bieber is gearing up for a major 2020.

The singer dropped his highly-anticipated first solo single in four years, "Yummy," on Friday, just over a week after announcing the single, a subsequent new album and North American tour in December.

While fans have to wait one more day for the song's music video, which will be released on Saturday, from the lyrics, it's clear that "Yummy" is an ode to Justin's wife, Hailey Bieber. Throughout the new song, Justin refers to his model wife as a "bona fide stallion," his "number one," "my lady" and "babe," among other things.

He also makes a not-so-subtle allusion to their sex life: "Rollin' eyes back in my head, make my toes curl, yeah, yeah," he sings at one point in the song.

"Yummy" is the first single off of his upcoming fifth studio album, due out later in 2020. While fans wait for the arrival of the album, they can catch Bieber in his upcoming 10-part docu-series, "Justin Bieber: Seasons," which will chronicle the last three years of his life, which involved some struggles, a break from music and, of course, marrying Hailey. The series, which will be available exclusively on YouTube, premieres on January 27.

Justin Bieber will kick off his 2020 tour in Seattle, Wash., on May 14.
