“I’m an actor and comedian, so I started #celestechallengeaccepted to make people laugh,” the star of Australia’s How Not to Behave tells PEOPLE. “I wanted to see how I would look if I attempted to recreate some really privileged peoples’ ‘everyday, normal’ selfies. I also like to challenge myself. I really thought I could do the splits like Serena – turns out, I can’t.”
Barber particularly enjoyed recreating Kim Kardashian’s risqué lingerie-in-a-dirt-pile photo.
“It was taken at a dirt bike track near my house,” says Barber. “When my friend Kelly and I went there to shoot it, there was a group of teenagers hanging out. I went up to them dressed in fishnet stockings, black heels and a big coat and said ‘I’m about to do something really inappropriate. You can stick around and feel uncomfortable or you can go.’ They left so fast it was kind of upsetting!”

While she hasn’t gotten any feedback from any of the celebs she has spoofed, she has a feeling the reality-star sisters would enjoy her split-screen creations.
“Imitation is the highest form of flattery, and I’m no expert but I think the Kardashian ladies are pretty happy for a bit of flattery,” says Barber, adding jokingly, “However, I take a fully detailed security team with me when I drop my kids at school, and I’ve got a new security system installed at my house incase Kanye comes knocking in the middle of the night.”
