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.
"I did cut the hair off a few of them." he confessed. "And I coloured her dolls' house in with Mum's lipstick."
"Probably to get me back for the time I coloured your face in with lipstick while you were sleeping," Emily chimed in.

"Art and I would get together when he had to make some tough decisions about who should stay or go!" she said.
"I need to know (whoever wins is) good enough for my little brother!"
The Bachelor's final episode screens on Wednesday night, 7.30pm TV3.
