The 'L&HH' star filed for divorce Monday in L.A. County -- and while the details of what she wants out of it are unclear at this point ... the fact she's calling it quits isn't. The only thing we know for certain is she notes there are minor children involved, and money's gotta be hashed out.

Worth noting ... she's the petitioner this time, and Ray's the respondent -- on their third divorce attempt, RJ was the one who filed ... and that was back in 2021. He also initiated their second divorce filing in late 2020 ... and she kicked it off initially in Spring '20.

So, they've kinda been going back and forth over who files ... this time, it's her doing it.

PL posted a lengthy statement on IG addressing the news, writing ... "It is with heavy hearts that we share the news of our decision to divorce. After much reflection, discussion, and counseling, we have come to the difficult realization that our paths have diverged, and it is in the best interest of both of us to part ways."

She goes on to say they're doing this with both of their well-being in mind, and that they're committed to being great co-parents to their two kids, a young daughter and son they share.

Princess Love asks for privacy over their divorce, finishing by saying ... "Though this chapter of our lives may be closing, we look forward to embracing the opportunities for growth, healing, and new beginnings that lie ahead. We are confident that with time, understanding, and the support of our loved ones, we will navigate this transition with grace and resilience."
