Kerry Washington's kids are beloved on the set of Scandal!

ABC star Katie Lowes stopped by ET for a Facebook Live interview on Thursday, and in addition to opening up about her ongoing battle with psoriasis, and Scandal's upcoming 100th episode, the brunette beauty raved about how much she loves her co-star's kids.

"We're, like, obsessed with them!" Lowes gushed of Washington's two children, 2-year-old Isabelle and 5-month-old Caleb.

Back in January, Washington dished to ET about how "lucky" she is that her kids are able to come to set with her. "I'm just so grateful for my job," the new mother-of-two said. "I'm so, so grateful that I get to do what I love to do, with people that I love, with scripts that I love -- the entire crew, it's such a family."

"It's hard to leave your family as a working mom," she continued, "but it's easier when you're going to a family."

"They're like our children. We're the Scandal family," Lowes echoed, adding that she loves her role as "Auntie" Katie. "Yes! And there's Auntie Darby. We're all aunties, of course. "

Lowes said that, much like Olivia Pope, there's nothing that Scandal's leading lady cannot do. "Kerry Washington is one of the most special individuals," she beamed. "She's a well-rounded person. Whether it's a charitable cause, or political cause, or acting, or producing, or all the levels of being a mom -- She's just not bad at anything."

"She is the epitome of grace and class and she's a dear, dear friend, but she's also a mentor to me," Lowes continued. "I was really new to the business when I booked this job and I was kind of like a baby gladiator in a suit, just like Quinn Perkins, and she really took me under her wing."

Over the past six seasons, Lowes has experienced an array of twists and turns as her character, Quinn, but she dished that there are still a few on-screen experiences she's been dying to check off of her Gladiator bucket list.

"There were some things that I hadn't checked yet, and that's what the 100th episode is all about. Trust me… This is beyond anything I've done on the show," she teased. "Literally, it was the greatest experience of my entire career. I'm just going to leave it at that."

Although Lowes has to be tight-lipped about the upcoming events on Scandal, the 35-year-old actress is opening up for the first time about a personal matter. "A lot of people don’t know this about me, but I've actually has psoriasis for the last seven years. I was diagnosed when I was 28," she said.

Lowes revealed that she got her diagnosis the same year that she booked her role on Scandal, adding that the stress from the added attention and spotlight helped trigger her symptoms.

After years of feeling "embarrassed" and "ashamed" of her breakouts and pretending that psoriasis was not impacting her life, Lowes revealed that she made a choice to become proactive about the disease.

"I was like, 'Oh my gosh I'm actually cancelling things in my life because of psoriasis,' and that's not a way to live," she said. "I feel so good that I have got my symptoms under control and I've got to a really good and accepting place with it, and that's why I can use my platform to help people."

For more information on her personal journey with psoriasis, Lowes encouraged her fans to go the website PsoriasisInsideStory.com. "It's really a place where we can all come together and empower each other to support one another and find a treatment that works for you," she shared. "Because, you guys, we should not be embarrassed. We should gather together, figure it out and live your best life."

Scandal airs Thursdays at 9 p.m. ET/PT on ABC.
