Shay Mitchell Recalls Getting Caught Clubbing, On 'When I Was 17'

Episode, also featuring Jeremih and Ashley Fink, airs Saturday at 11 a.m. ET/PT on MTV.

It's almost a quintessential American high school rite of passage: Get a fake ID, and sneak into clubs with your girlfriends for the night of your lives. That was certainly the plan for Shay Mitchell, but it all went horribly wrong, as the "Pretty Little Liars" star shares on this week's "When I Was 17."

"I would say I was a pretty good girl, but there happened to be this one night when a group of my friends decided to go out to this club. Of course, we weren't of age, so we snuck out, and I think each of us told our parents that we were staying at the other person's house," Shay recalls.

With their alibis settled, Shay and her girlfriends headed downtown and successfully entered a club with their fake IDs.

"We were dancing and having the best time ever. All of a sudden, I'm dancing with some really cute guy, and I feel a tap on my shoulder," Shay continues. "I turned around, and this person says, 'Can I have this dance?' "

And who was this mystery man asking her for a dance? Turns out, it was her father.

"I was in complete shock. Never in a million years would I have thought he would've come and find us," she says.

Her friend, Jody, explains how Mr. Mitchell managed to sleuth out their location: "[He] found out because my mum had called their house because she thought we were there. No one answered, and I guess all the parents put the pieces of the puzzle together."

Shay describes the hilariously pathetic way she and her friends made their exit. "We walked out the club like sad little ducklings with our heads down," she remembers.

Of course, there were serious consequences for Shay after that night. She was grounded for two weeks, and also had her car keys taken away. But she learned her lesson for sure.

"I definitely didn't ever do that again," she says.
