On Thursday, the Aussie actress posted a snap of her derriere with the caption, “Australia you cheeky possum!”

In May, Wilson, 40, revealed her target goal of 165 pounds.

“Even if you have to crawl towards your goals, keep going x it will be worth it,” she captioned a photo of herself in a tracksuit and bra. “Try and give a little bit of effort each day…I know some days are frustrating as hell, you feel like giving up, you get annoyed at the lack of progress…but good things are coming your way.”

In December, she revealed she dropped eight pounds in four days while working on “Cats.”

Wilson is also revamping her love life declaring that she has been dating “a lot.”

“I don’t think I’ve found the right person,” she told News.com.au in June. “But I’ve been dating everyone from billionaires to the very regular person next door. It’s been fun meeting different people.”

She continued, “I’ve turned into such a romantic. I’m not ashamed to admit that I watch and love shows like ‘The Bachelor’ and ‘The Bachelorette.’”

The “Isn’t It Romantic” star joked that her asking price is $20 million to appear as the next Aussie ‘Bachelorette,’ but did concede that she would make an intriguing choice.

“I think it’d be interesting to represent a more real-looking woman as the ‘Bachelorette,’” she said. “I think that’d be a really positive message and I think people would find it more interesting.”
