Keeping up with the ever-evolving mysteries on Pretty Little Liars is no easy feat, but Shay Mitchell (Emily) is letting us into at least one of her real life secrets: Her trick to staying energized.

"This is a "black eye" from Starbucks — a large coffee with two shots of espresso. Thank you, Starbucks for my "black eye" today. #ifonlyyouknew," Shay tweeted yesterday (April 2), along with a photo of her personalized coffee cup. We're hyped up just looking at it!

As for why Shay needs to be heavily caffeinated? The brunette actress is busy filming for Pretty Little Liars Season 4 and even woke up at 4:30am (gasp!) for a recent call time.

Bring on that espresso!  

Pretty Little Liars
Season 4 premieres on Tuesday, June 11, 2013 at 8 p.m. ET/PT on ABC Family.
