Rebel Wilson turned up the heat for her followers.

The “Pitch Perfect” star sizzled in a lime green bikini on Saturday while hanging out in a hot tub.

Wilson, 40, originally captioned the photo on Instagram “Hot Tub Fine Machine,” according to People, in reference to the movie “Hot Tub Time Machine.”

The “Isn’t It Romantic” star received her law degree in Australia after working to graduate for five years.

“I’ve never practiced for money, but I could if I wanted to. If it doesn’t work out in movies,” Wilson said during an appearance on “The Late Late Show with James Corden" in 2019.

The Australian actress continued: “I play a lot of dumb characters so people were very confused about what I was doing in the contract law exam. It took me so long to get into law school, you have to study really hard, so I thought I may as well finish it even though I was already kind of famous. So I did.”

Wilson’s latest bikini photo comes months after she revealed in January that she was embarking on a “Year of Health” journey to lose 75kg, which is roughly 165 pounds.

In May, the Australian actress opened up about her progress in a candid Instagram post.

“Even if you have to crawl towards your goals, keep going x it will be worth it. 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,” she began.

Both of these things are requiring a daily effort and there’s constant set backs -- but I’m working hard.”
