With all the female attention One Direction have been getting, it's no wonder they'd be concerned and careful about STDs. But no one expected they'd be at risk from getting an infection from someone named Kat ... especially when Kat is a koala. Say what?!

The Huffington Post reports that during the band's recent trip to Australia, Harry Styles and Liam Payne held an adorable koala named Kat. Kat apparently was a hardcore Directioner herself and got so excited to see the 'What Makes You Beautiful' singers that she, well, relieved herself on Payne and Styles. Under most circumstances, one would just wash everything off and move on, but koalas bring with them a different risk: chlamydia.

About 80 percent of koalas have the disease, with its symptoms including severe pink eye, incontinence (which may explain poor lil' Kat's accident), kidney damage and psoriasis. Not all koalas exhibit the symptoms of the infection, but it's leading many female koalas to be infertile, which could potentially lead to extinction of what may be the cutest creatures on the planet. Nooo!

While koala-to-human transmission of the illness is rare, it's still possible -- and the boys are reportedly pretty spooked about it.

"I'm genuinely scared. This is worrying," Payne said. "I’d have never picked the thing up if I'd known."

Here's hoping they don't have to say the same thing about girls on the road!
