We've all had a crush on Zac Efron at some point in our lives... And if you say you haven't, then you're lying to yourself and everyone around you.

Though he first rose to fame as the cute adolescent Troy Bolton in Disney's High School Musical franchise, he has now grown to become one of the biggest heartthrobs of the decade.

And he certainly knows how to get his fans hot under the collar. The actor recently posted a photo which shows him relaxing - half-naked, might I add - in a sauna. It's all very steamy and sensual, as you can imagine. However, there's one thing that eagle-eyed Efron lovers have noticed... You can blatantly see, what fans believe to be his manhood, through his shorts.

Do I even need to tell you to keep scrolling?

We've enjoyed over a decade of Zac Efron goodness.

Zac Efron first came into our lives in 2006 as the fresh-faced, sparkly-eyed teen, Troy Bolton.

He was the ultimate teenage heartthrob.

And young girls all over the world instantly became obsessed.

And, after his success in High School Musical...

Efron went on to play a number of other roles of a similar nature, including another teen heartthrob, Link Larkin in the remake of the 1988 musical, Hairspray.

However, as he got older...

Zac dropped his younger, more adolescent Disney image, and began taking on more mature roles.

The teenager we once knew and loved was gone...

And there was now a strapping young man stood in his place.

He began appearing in many more R rated movies...

Including crude comedies such as Dirty Grandpa and Bad Neighbours.

Oh, and we can't forget the time he starred in the Baywatch remake...

I would quite happily get swept out to sea with this delightful combination...

And the most impressive part about his role in Baywatch?

The actor managed to build his "Baywatch appropriate" body in just twelve weeks when he was in training for the role.

But, in more recent times...

The actor has ditched the abs and ventured into much darker territory with his portrayal of the notorious serial killer, Ted Bundy.

Extremely Wicked, Shockingly Evil and Vile told the story of the demented killer...

And depicted the journey of Ted and his girlfriend, Liz, as he is captured and accused of his many murders.

And, yes, Zac did the impossible...

He managed to make thousands of women suddenly become attracted to a serial killer... Despite his lack of Baywatch abs. If that isn't a skill, I don't know what is.

And people were going that crazy over the new, and "hot" Ted Bundy...

That Netflix had to step in to gently remind everyone that Ted Bundy was, in fact, a demented serial killer and rapist, and that there were plenty of other "hot" actors to drool over on their streaming service.

To cut a long story short...

Zac Efron is an incredibly attractive man. There, I said it.

And his Instagram account is usually one big thirst-trap.

And, with his 40.5 million-strong following, his half-naked selfies are obviously working.

But his latest post has caused a little controversy...

Because fans are convinced that he accidentally revealed his manhood. Yikes.

Here it is, ladies and gents.

The incriminating photo, in its full glory.

Still don't see it?

Okay, take a closer look at Zac's crotch (we're awful people, aren't we?).

Many people were thrown off by the mysterious shape sticking out of the elastic of his pants...

One said, "What's coming out of his pants?" While someone else joked, "I had to do a quick little double-take and zoomed in on this picture." But, oh... It turns out to simply be the elastic string of his shorts.

False alarm, everyone!

Though his fans were still thirsty as hell, with one social media user even stating that she wants the actor "to ruin her life". Fair enough...

But some people were more distracted about Efron's sauna technique...

I mean, who even wears shorts into a sauna?! But this isn't the first time people have lost their minds over a deceiving photograph of the actor - Keep scrolling to read about the time a picture of Zac riding a horse caused his fans to completely lose their minds...
