Later on Monday, December 1, Leah revealed that she has resumed working on the show's second season.

"@matlockcbs ❤️And we back up and running," she wrote on her Instagram story, accompanied by a picture of her dressed up as her character, lawyer Sarah Franklin.

According to the outlet, after Rio got fired from the show, CBS also confirmed that his character would be written out of the series, and a separate source said that his character will not return in future episodes.

Leah Lewis breaks her silence after David Del Rio departs from Matlock

After the news of David Del Rio's departure from Matlock broke, Leah Lewis shared a photo of her and her mother on her Instagram story, writing:

"Mom is here, we’re moving forward in love and strength. I’m in good hands. Thank you to everybody for any kind of support and care. Truly, we’re moving forward in strength. Key word, strength. Please, let that be the takeaway."

Although David Del Rio has yet to publicly comment on the situation, his wife, Katherine, shared a photo of Lewis on her Instagram handle in a now-deleted post, writing:

"This is the most disturbing human being I have ever met."

The couple share two daughters, Lilia and Coco.

Meanwhile, addressing the situation, David's friends in a statement to US Weekly in October, said:

"His wife is standing by him. They’re a family and staying together."

Leah Lewis, who is best known for her roles as Ellie Chu in The Half of It and Georgia Fan in Nancy Drew, was raised in Windermere, Florida, by her parents, Lorraine and Frederick Lewis. She was adopted from a Chinese orphanage at just 8 months old, per her IMDB page.

The 29-year-old is candid about her fitness journey on social media, regularly sharing her progress with her 3,000,00-plus Instagram followers. She recently wrote about how working out has helped enhance every aspect of her life.

"You train your body, but then it trains you to go out and do much more than that. It's all connected. This sentiment shows up in every other area of my life when I suit up, shut up, show up, and then wait for the magic. SSS. Especially when I just don’t feel like doing it, or it’s hard to see the end goal, it’s not magical. At all actually. Sure, it could just be the physical product of the efforts you put into your health, these are what these photos show, but it’s also taking the challenge in other ways. Showing up in one place consistently, can move you to show up in other daunting places that feel like "so much effort," she wrote.

Lewis also auditioned for The Voice in 2013, performing Carrie Underwood's Blown Away, but did not make it onto the show.
