David Muir and Deborah Roberts bid an emotional farewell on Friday when they revealed a big change to their 20/20 show.
Taking to Instagram, Deborah posted a photo of herself outside the ABC building in New York.
She shared a lengthy post explaining the team was moving on.
"Friday finish," she began. "Nearly 3 decades after I first set foot in the ABC news headquarters as a new correspondent, the youngest to join the 20/20 team, we are officially saying goodbye to the building."
She continued: "The place where network TV legends walked the halls and delivered the news. I was thrilled and a bit nervous to join Barbara, Hugh, Peter, Carole, Joan, Charlie and a cadre of inimitable correspondents. What a moment."
Deborah elaborated when she wrote: "Now, a bright, shiny space awaits us downtown to continue the great work we all love so passionately. Change and goodbyes are always hard for me. I am comforted by routine and the familiar. But change is the only true certainty of life, right? So here we go… making new memories @abcnews."
Deborah joined 20/20 as David's co-anchor in 2023 — replacing Amy Robach — but she has been a contributor since 1995.
The pair have great on-screen chemistry, something which hasn't gone unnoticed by Deborah's husband, Al Roker.
During an interview with Entertainment Tonight's Spilling the E-Tea, shortly after they began working together, the Today meteorologist told his wife: "I think you're doing great, you know? …In fact, the chemistry almost seems a little too goodHe then continued: "You both adore each other, and I think the show is now to the next level."
At the time, she said of her new role: "It is something that gives me a feeling of accomplishment and great pride."
When she shared the news with fans, she posted a a portrait of herself and David and penned: "I have some news to share. I am thrilled and humbled to step into the role as co anchor @abc2020 alongside my friend and colleague @davidmuirabc.
