On Monday, Vieira announced that she plans to exit NBC's morning news programme in June in order to spend more time with her family.
In an interview with Access Hollywood, Curry said that she is delighted to be joining Lauer as one of Today's hosts, but added that it is "bittersweet" because the promotion is a result of Vieira's exit.
"I feel like I am the computer nerd in high school who was just asked to the prom by the quarterback on the football team, I mean, think about it: he's the quarterback… Who is better than Matt Lauer?" she joked. "He is really unbeatable [and] to have him say, 'I want you to sit next to me and help me say hello to America every day' is such a huge [deal]."
The journalist later added of Vieira: "She could not be a more generous friend and the first response I had when I was offered this job was, 'I'm really excited'… And the second response was, 'How do we keep Meredith? What is it we can do?' I don't want to wake up every morning without her… It's [that] part of my day that I don't want to miss… having her as a friend."
Curry, who has delivered headlines on the NBC morning show for more than a decade, also admitted that it was difficult to be passed over when previous host Katie Couric left Today in 2006.
"There was a little [hurt]. I wished for it, I wished to be asked, I did, I did," she revealed. "But, I really like her and I really loved the show… We fell in love with Meredith and it wasn't hard to adjust. In fact, if I wasn't offered this job I don't think I would have gone anywhere, I mean, the truth is I love what I do so much."
She continued: "Nobody's owed anything. This is about doing the work. It's not about us, it's about the people who watch and it's all about taking care of them and the people who watch is what's important."
Her future co-anchor Lauer recently confirmed that he engaged in discussions about reuniting with Couric for a syndicated talkshow, but eventually resolved to stay on at Today.
