The weird and wacky world of showbiz wouldn't be the same without the frequent eccentricities.
But even Paris Jackson has confessed she initially thought wearing masks in public was 'stupid'.
Her father Michael Jackson would frequently cover his children's faces, in a bid to keep Prince Michael, 14, Paris, 13, and nine-year-old Prince Michael II out of the prying eye of the paparazzi lens.
It seems protecting their identity from the public had the desired effect though, and when Paris arrived at The Buckley School - no one knew who she was.
She said: 'I do have a regular childhood. I mean, I'm treated the same. When I came to (my new school) they didn't know who I was. I was like, "Yes, I have a chance to be normal."'
Yet now the rising star is chasing fame and recognition by landing her debut role in a film series.
Jackson will play the heroine in fantasy picture Lundon's Bridge And The Three Keys, based on the young adult series by novelist Dennis H. Christen.
She added: 'My dad was in the movie Moonwalker and I knew he could sing really well but I didn't know he could act.
'I saw that and I said, "Wow, I want to be just like him." I was little. I was younger than Blanket (their nickname for sibling Prince Michael II).'
