It's #MCM: Why Zac Efron And His Six-Pack Make Us Swoon

He's up for Best Shirtless Performance at the MTV Movie Awards, and here's why.

He's one of Hollywood's hunkiest leading men who can sing, dance and act. Not to mention, he has a ridiculous set of six pack abs, and I mean ridiculous. Of course we could only be talking about the one and only Zac Efron, MTV News' pick for this week's Man Crush Monday.

Now, Zac isn't afraid to show off those abs, I mean, why would he be when he looks that good? We got our first glimpse of Zac's toned tummy way back during his "High School Musical" days, after that he made us wish we were "17 Again" or at least be "The Lucky One."

However, there was that kind of "Awkward Moment," where Zac bared all on top of a toilet, but we can totally get past that.

Yet, in each of these instances, Zac's star shined bright, along with his abs, which is why he is nominated for an MTV Movie Award for Best Shirtless Performance. And get this, if he wins he promised to accept his golden popcorn shirtless, so I highly suggest you keep voting because the Movie Awards go down this Sunday, April 13 at 9 p.m. ET/PT.

In case you need convincing as to why Zac is nominated for Best Shirtless Performance or a just want a refresher, at what he looks like with and without his shirt on take a look at the GIFs below!
