Gesine Bullock-Prado Once Spoke About Their Age Gap

Sandra Bullock and Gesine Bullock-Prado eventually became creative collaborators.
Gesine, 56, who is six years younger than Sandra, 62, has previously spoken openly about how their relationship evolved in an interview with The Guardian.
“Our age difference made it impossible to be chummy when we were younger. I was a pest, an annoyance of a younger sister. No girl in her tender years, navigating through the trials of puberty wants her annoying geek of a little sister hanging about … It wasn’t until I got older that the age gap disintegrated. Once I was in high school, we became genuinely close,” she said.
