“The Good Wife” star Mamie Gummer is now an estranged wife … because she just pulled the plug on her marriage.

Meryl Streep‘s oldest daughter beelined it to court Thursday and filed to divorce her husband Mehar Sethi after 6 years of marriage.

In the divorce docs, obtained by TMZ, Mamie lists the date of separation as May 6, 2023 … and she’s going with the boilerplate irreconcilable differences as the reason for the split.

Mamie is seeking joint legal and physical custody of their 5-year-old son Peter and 3-year-old daughter Mary.

She’s also seeking spousal support and checked the box to terminate the court’s ability to award support to her estranged husband.

Mamie and Mehar, a writer, tied the knot in February 2019 … and, two weeks later she gave birth to their first child.

This is Mamie’s second divorce … her first marriage was to actor Benjamin Walker.

Meryl and Don Gummer announced their separation in September 2023 … and in March 2020, Mamie’s sister Grace Gummer filed for divorce from her husband.

Alix Earle is making big moves with a sexy new commercial for this year’s Big Game … and Winnie Harlow is continuing her rise from supermodel to skin care mogul.

Winnie’s been in the modeling game for a while now, and she’s still at the top … but Alix is quickly climbing the mountain … so, we gotta ask … Who’d You Rather?!?

Rihanna‘s back at it, rocking everyone’s world as she left the downtown L.A. courthouse where her man A$AP Rocky is going through his criminal trial.

The singer kept the style parade going, wearing a trench coat and tan boots as she was filmed leaving the courthouse with a bodyguard Thursday … her fourth time supporting her partner at trial.

Of course, her presence isn’t low-key — it’s RiRi, so the media hoopla was inevitable. She knew it was coming, so she flew under the radar on day one, slipping into the courthouse undetected, but since then, she’s had to enter and exit through the regular areas.

Once inside, things have been chill — she’s been seen sitting with his family, including his mom and sister, as the trial’s been moving forward.

A$AP Rocky’s on trial for allegedly shooting his former friend A$AP Relli during a heated 2021 showdown in Hollywood.

The D.A. slapped Rocky with two felony assault charges after his 2022 arrest at LAX … only moments after the plane he was flying on with Rihanna touched down from their trip to Barbados.
