As the NCIS franchise cemented its place in the television hall of fame with 1000 episodes, Vanessa Lachey also made history as its first female lead.

The actress, who currently leads the NCIS: Hawai'i series as Jane Tennant, exclusively tells PEOPLE about what it's meant to be a part of the millennial milestone as a groundbreaking addition to the crime-fighting family. Her character has been taking charge since the show debuted in September 2021.

"It’s an honor to be able to add to this incredible franchise and to do it as the first female lead has meant more to me than I can ever express," she reflects. "It shows the incredible evolution and longevity that NCIS continues to give its fans."

Lachey says getting to have a "family" both "across the generations as well as continents" is what she loves most about being a part of the NCIS universe.

"Not only with our cast but the fans as well," she adds. "The NCIS franchise is all over the world and it brings people together to watch and talk about, as well as provide comfort and entertainment, which is what you want when you dive into a show."

Shortly after landing the role, she and her husband Nick Lachey relocated to the Aloha State — where the show films on location — along with their three kids: Camden John, Brooklyn Elisabeth and Phoenix Robert.

In September 2021, Lachey revealed her husband had the "most supportive thing he could have said" when she broke the news of her casting.

"I just gave him the biggest hug," she recalled. "He said, 'This is your time. And I will do whatever I need to do to support you in that. I've seen you work so hard. This is your time. Let's go.' And I'm like, thank you!"

In March, Lachey told PEOPLE that the season 3 episode won't just serve as a reminder of how far the franchise has come and to "kick off the next 1,000" — it'll also be a way for her to reflect on her own past.

Calling the episode a "full-circle moment," she explained, "It dips into my mother who abandoned me. It is a very emotional episode, it is a very deep episode."

"It's actually Daniela Ruah, the actress on NCIS: LA, directed it. " lot of stuff happens, and I'm nervous. I'm always going to be nervous," she said, confessing that she feels nerves because she's taken on more light-hearted roles in her career.
