After almost five years after the wedding, the couple announced that they were expecting a daughter.
The news came as a surprise for fans as Sixx has previously gotten a vasectomy following his 2007 divorce from his second wife, actress Donna D'Errico.
Sixx shared that he got a vasectomy because he did not want to live the rest of his life in court fighting over child support.
But then everything changed when he met his spouse.

The couple started planning for a baby, and it appears the pregnancy was possible after the bassist underwent a sperm-retrieval procedure.
He and his spouse then used artificial insemination to conceive.
On July 31, 2019, Sixx took to Instagram and announced the birth of their daughter, Ruby Sixx.
The new mom shared that their daughter entered the world after 18 hours of labor in a separate post.
"I am so excited to be a mommy and know Nikki will be the most wonderful daddy ever, just as he has been with my four step-children." wrote Bingham.
