Leah Remini‘s officially filed to divorce her husband … and, it looks like she’s taking cues from her on-again, off-again friend Jennifer Lopez — ’cause she did it sans lawyer.

The actress filed the documents late Thursday night … citing irreconcilable differences as the reason she and Angelo Pagán are calling it quits after more than 2 decades of marriage.

LR listed the date of separation as August 1 and checked the box to block the court’s ability to award either of them spousal support. While the 2 share a daughter, Sofia, she turned 20 in June … so no question of child support.

The big news here … Remini filed the docs pro per, meaning she did it without a lawyer — just like J Lo did earlier this month when she filed to divorce Ben.

Remember, Leah and Jennifer have been friends for years … though some outlets reported the 2 had a falling out around the time Bennifer tied the knot … and only recently reconciled.

We do know Leah Remini chose to skip Jennifer and Ben’s wedding to hang with her daughter before she left for college … a bit of a slight given how close the 2 ladies have been for years.

Remini announced her plan to file for divorce Thursday … announcing a lot of thought and care went into ending the nearly 30-year-long relationship — saying the 2 realized they’ve changed a ton and no longer fit together.
