Jennie Garth has vowed to support Tori Spelling amid her divorce from Dean McDermott.
Tori, 50, has filed for divorce from her husband of almost 20 years, citing irreconcilable differences as the reason for their break-up and Tori's 'Beverly Hills 90210' co-star Jennie, 51, said she will be there for her pal.
Jennie told PEOPLE: "I've always stood beside her, behind her, supported her, and I will always continue to do that.
"We bonded, [and] forged a really strong, unique friendship at such a young age. That kind of bond doesn't ever go away. You know, it's kind of unbreakable."
And, Ian Ziering, 59, added that working together on the show had bonded the cast for life.
He said: "We support each other through life's ups and downs after the show, we still care about each other. So whenever there's a victory, we all pull together and lend support and pride, and when there's challenging times, we come together and offer whatever support we can from wherever we are.”
In court documents obtained by PEOPLE, Tori and Dean's official date of separation was listed as June 17, 2023.
Tori asked the court to award her spousal support and to terminate her husband's ability to receive the same support.
The actress - who has Liam, 16, Stella, 15, Hattie, 11, Finn, ten, and Beau, six, with Dean - is also seeking sole physical custody of their five children.
The court filing doesn't specify whether the celebrity duo - who have been married since 2006 - have a pre-nuptial agreement in place or not.
Dean actually announced their separation on social media on June 17, which is the date listed in Tori's divorce filing.
The 57-year-old actor took to Instagram to share the news with his followers, before he deleted the post.
Dean - who was previously married to Mary Jo Eustace between 1993 and 2006 - wrote on the photo-sharing platform at the time: "It’s with great sadness and a very very heavy heart that after 18 years together and 5 amazing children, that @torispelling and I have decided to go our separate ways, and start a new journey of our own.
"We will continue to work together as loving parents and guide and love our children through this difficult time. We ask that you all respect our privacy as we take this time to surround our family with love and work our way through this. Thank you all for your support and kindness."
