The Bachelor's older sister, Emily Green, says her younger brother is "geeky" - and says she's still not used to seeing Art's face - and body - plastered on billboards around the country.
"It is weird" Art's sis reveals to Woman's Weekly.
"I'm driving along, and all of a sudden I see Art on a billboard. Then I get to the gym, and it's 'Oh! There's Art's face in an ad!"
She added: "You wouldn't think it now, but he was my geeky little brother for a long time."
Talking to Woman's Weekly about their childhood, Art let slip that he would terrorise his sister's Barbie dolls when they were younger.
