Adam Levine is ready to say sorry.

The “Voice” mentor, 35, has an important mission to complete before marrying model Behati Prinsloo: apologizing to his exes.

Before his July nuptials, the perpetually stubbly crooner is reaching out to his illustrious group of exes — a group that includes models Anne V. and Nina Agdal — and asking for their forgiveness, reports Us Weekly.

“He apologized for how he treated them,” an unnamed source told the magazine.

Unfortunately for the Maroon 5 frontman, not all of his past lady loves are having it.

“They couldn’t care less he wants to make it right,” another source said.

According to the magazine, that may be because Levine wasn’t a particularly good boyfriend. He reportedly broke up with Agdal by avoiding her calls, then informing her of his engagement via text.

In addition to his apology spree, People’s reigning Sexiest Man Alive plans to get a permanent reminder of his love for Prinsloo, 25, inked onto his body.

“He may get a tattoo of Behati’s name over his heart,” yet another anonymous source told the magazine. “He wants to make their love permanent on his body!”
