In Sin City for Sunday's Academy of Country Music Awards, the show's co-host had quite the opportunity to indulge his, um, sinful side.
"The first night we got to Vegas, me and Sheryl Crow and Miranda and Angeleena went to Miranda and Blake's room and had a spray-tan party, so all of us were naked," Monroe, 26, told PEOPLE on the pre-ceremony red carpet. "We made Blake go upstairs and close his eyes."
And while what happens in Vegas may stay in Vegas, Shelton was a true Southern gentleman about it.
"He left," she said, adding, "but there could have been a camera! I'm still not sure. We'll see what he Tweets in the next week."
