HOLLY Willoughby has been hit with some very cheeky comments after her latest post.

The I’m a Celebrity… Get Me Out of Here! presenter posed with a cute koala bear on her Instagram page.

However, Holly Willoughby’s adorable snap was floored with a host of STI comments from fans.

Many asked Declan Donnelly’s I’m A Celeb co-host if she knew that koala’s carried chlamydia.

One asked: “You do know that koalas have chlamydia?”

“You do know that koalas have chlamydia?”

While another stated: “They have chlamydia.”

A third warned: “Watch out they have chlamydia.”

Scientists say the strain of chlamydia that infects koalas is not the same that infects humans.

However, it is sexually transmitted in the same way.

As well as hanging out with a koala, Holly, 37, was also seen feeding some kangaroos.

Witnessed by her 4.6 million followers, the blonde wrote: “Willoughby, wallaby, wobbly… I’m aware it’s a kangaroo.”

Holly also caused a stir with her outfit on last night’s I’m A Celeb.

Fans accused the star of dressing as a ‘cowgirl’ in high-neck check shirt and denim and leather hybrid skirt.

I’m a Celebrity… Get Me Out of Here! airs nightly on ITV at 9pm.
