These lips were made for talking.

Jessica Simpson, 44, who announced her divorce from husband Eric Johnson, 45, in January, dropped her new single “Leave” on Friday.

The breakup song — off of her upcoming EP “Nashville Canyon: Part 1” — hints at the demise of a relationship due to infidelity.

Simpson, who is currently 44 years old, expresses the sentiment that their previous relationship was enchanting but has now turned sorrowful. This change is attributed to the fact that the person he was involved with is now receiving the same gestures and attention that were once devoted to him. As a result, there is a sense of emptiness and depletion in the emotional connection that was once significant.

“Your weakness made me lonely / Unholy matrimony / Did you do to her what you did to me? / Was she on her knees?”

Later in the tune, the actress belts out that she would rather be by herself.

“We’re not doing this again / I, I want you to leave / I don’t even want to breathe the air you breathe /I’d rather die / Than let you be inside me with her on your mind / I am stronger on my own / So I’m letting you go.”

Simpson got candid on the making of “Leave” in a behind-the-scenes YouTube video.

“Leave is a hard lyric for me to write,” she admitted in the Friday clip. “It was tapping into some stuff that was scary to tap into. But I needed to get it out.”

“After writing all the lyrics and the melodies I realized like ‘Why would I want to show off,’” Simpson continued. “There’s so much power in being able to be subtle. And that’s probably the best lesson I’ve had in this whole process. Is that, music is about communicating, not yelling at people.” 

In January, the artist announced she and Johnson were divorcing 10 years after tying the knot in 2014. They are parents of three kids: daughters Maxwell, 12, and Birdie, 5, and son Ace, 11.

“Eric and I have been living separately navigating a painful situation in our marriage,” Simpson told People at the time. “Our children come first, and we are focusing on what is best for them. We are grateful for all of the love and support that has been coming our way, and appreciate privacy right now as we work through this as a family.”

And in the wake of the split, the “Irresistible” singer has turned back to music to help her get through.

“Through the deepest heartbreak of my life,” Simpson told sister Ashlee Simpson in an interview with The Cut in February. “It was the most intense yet enlightening therapy I’ve ever been through.”

She also expressed her gratitude for the former NFL player as he supported her spending time in Nashville creating the project.

“It is a gift,” Simpson noted of taking time to work on the EP. “Eric supported that gift. My kids supported that gift. We were out in Nashville for Maxwell’s 11th birthday, and she’s 12 now.”

The Post was not immediately able to reach Johnson for comment.
