Jason Derulo sure isn’t shy about putting it all out there.

Fans went wild after Derulo took to Instagram this week with a sexy photo of himself in teeny-tiny briefs, showing his rock-hard abs, chiseled arms — and a noticeable bulge in his pants.

His Instagram account was flooded with lusty comments and eggplant emojis, with one fan commenting, “Sweet Mary mother of god👀🍆,” while another gawked, “get a zoom in on that 🔥🔥 damn!”

When one fan joked, “What animal are you hiding in your pants?” the pop star responded, “Anaconda.”

The 30-year-old works hard for his ripped body, initially running track in high school as a way to lose weight — and meet girls. “What I did have was the mental toughness to work harder than everyone else,” the “Cats” star recently told Men’s Health. “I started off chubby, and, by the end, I became amazing.”

The singer, who today weighs about 190 pounds and measures 6 feet tall, told Men’s Health that because he eats so much, he is very strict with his diet, which includes the intermittent fasting and a lot of protein. He likes to shake up his workout regimen, doing anything from boxing to jumping rope to snowboarding to car-pulling.
