Lachey made history when she was cast as the franchise's first female lead last year. Her character Jane is also the first woman to be named the Special Agent in charge of NCIS Pearl Harbor.

She said she "will never forget" the day she landed her next big role.

The actress took to her Instagram account after the announcement, posting a very emotional selfie video taken moments after she found out she had landed the role.

"I'm so happy," she continued, before being overcome by a fresh round of sobs.
