Besides his daughter, Sixx has four other children from his previous relationships.
He was first married to Playboy playmate Brandi Brandt in 1989.
According to reports, when Brandt and Sixx got together the first night, the rocker received a call from Brandt's mother, Brie Howard.
It appears Sixx and Howard used to "roll around together" while Mötley Crüe was on tour. But that didn't stop Sixx and Brandt from starting a relationship and getting married.
The former couple welcomed three children: sons Gunner and Decker, born in 1991 and 1994 respectively, and daughter Storm, born in 1994.
In 1996, they filed for divorce, and Sixx gave her their house.
A month after Sixx divorced Brandi, he married his second spouse — another Playboy playmate, Donna D'Errico.
They welcomed their daughter, Frankie Jean, in 2001. But in 2007, they filed for divorce, citing irreconcilable differences.
Their divorce was far from amicable, but they eventually reached an agreement for the sake of their daughter.
