The 35-year-old actress, who starred in eight seasons of original TV series, "Full House" from 1987-1995, says she has known them from the time she was around five years of age, reported E! Online.
"I've known them for 31 years of my life. I think it's kind of hard to put into words what they mean 'cause they really are my family, other than my parents, and my actual, legitimate family, there's nobody else in my life I've known longer than these people," says Sweetin.
The series will premiere this year on the streaming website.
