Wait, did someone just poop their pants?

Ariana Grande and Demi Lovato decided to go for thrills over chills Friday night when they kicked off their weekend with a wild adventure.

As the pop superstars embarked on an evening hike to a special house, they got a little more than they bargained for.

"Friday night was lit and by lit I mean terrifying because we hiked on foot to the Manson murder house," Ariana shared on Twitter before revealing Demi was by her side. "Bye."

She continued, "@DDLovato and by lit we mean everyone shat themselves." Oh yes, she went there.

But wait, there's more. Demi took it one step further on Twitter to share her memories of the night.

"@ArianaGrande and by shat ourselves we mean we literally s--t our pants," she wrote. "Except yours had glitter in it. And the Chanel logo." Well, pooping your pants is always better than having a "Heart Attack." Are we right, Demi?

The late-night fun came just hours after Demi impressed millions of viewers with her appearance on The Tonight Show Starring Jimmy Fallon. While playing "Wheel of Musical Impressions," Wilmer Valderrama's leading lady nailed impressions of Christina Aguilera, Cher and Fetty Wap.

While some of us may need a day or two to recuperate after such an eventful Friday, Demi was more than ready to conquer another day. Forget about any nightmares. It's time to break a sweat!

"Dear Saturday Morning, I'd love to sleep in with you, but I love and respect myself too much to go back on my commitment to working out!" she wrote on Twitter.
