Shannen Doherty knows what it’s like to have her personal life on display – so she can relate to what former 90210 costar Jennie Garth is going through with her very public split from husband Peter Facinelli.
“I think that for somebody like Jennie who values family so much, this is incredibly hard for her,” Doherty told PEOPLE Thursday on a conference call for reporters to promote her new reality show, Shannen Says.
“I feel for her and, more importantly, I feel for her kids,” she continued. “There are children involved [and] children have access to the Internet and everything that somebody may write.”
“I happen to watch Tori’s show and I think it’s incredibly charming and endearing and I can’t wait to see Jennie’s show,” Doherty told reporters. “I think [it’s] gonna be great.”
“I did the new 90210 with Jennie and there was something very different about our friendship,” she said. “We were able to look at each other as grown women and really acknowledge that we like who the other person was now, as adults.”
As for her other former castmates, “I speak to Brian [Austin Green] all the time and I saw Ian [Ziering] a week ago and it was awesome,” she said.
“He’s a sweetheart and he stays so young looking, it’s ridiculous,” she added with a laugh. “I’m incredibly jealous.”
Doherty’s new reality show – which chronicles her road to the altar with now-husband Kurt Iswarienko – premieres on WEtv April 10 at 10 p.m. ET.
