Adrianne Palicki has filed for divorce from Scott Grimes for a second time.

More than a year after the actress first filed for divorce from her Orville costar, she once again filed to legally end their marriage on July 16 in Los Angeles Superior Court, according to court documents obtained by PEOPLE.

The documents cite "irreconcilable differences" and their date of separation is listed as June 9, 2020.

In shared statements posted to their respective Instagram accounts on Thursday, Palicki, 37, and Grimes, 49, confirmed their split to fans.

"So thankful for our time as a couple, even more thankful for our deep, everlasting friendship. Love you SG," Palicki captioned a photo of the couple.

Grimes wrote alongside the same image: "So thankful for our time together as a couple, even more thankful for our deep everlasting friendship. Love ya AP."

According to court documents obtained by The Blast, the new filing comes a few months after she reportedly dropped the original divorce filing. In July 2019, Palicki first filed to dissolve their union after two months of marriage.
