The Liars can have some pretty long days trying to juggle their hunt for “A” with their busy social lives, but the actresses who play them put in some long hours, too. A few weeks ago, we shared Shay Mitchell’s (Emily) tweet chronicling her 5 a.m. call time. Last night, Shay was filming Season 4 with co-star Ashley Benson (Hanna) well into the evening. What time did she tweet from set?

“Werk. RT @AshBenzo: Late night shoot with shaymitch,”  Shay tweeted at 11:38 p.m. Let’s just hope for her sake that her morning call time was a bit later than it was a few weeks ago! Shay also tweeted a pic of her and Ash, proving that the girls can look glamorous (and be cheerful) at any hour.

We wonder what the girls were filming...The cast and crew recently wrapped filming on the first episode of season 4, “'A' Is For A-L-I-V-E,” so we’re guessing it is Season 4, Episode 2: “Turn of the Shoe.” And, coupled with this adorable pic of Shay giving Ash a piggyback ride on set during the filming of the premiere, it looks like we’ll be getting lots of Hanna/Emily scenes in Season 4!

PLL executive producer told Zap2It that Hanna was “A”’s main focus come Season 4, so we’re a bit worried about our favorite blond-again Liar! Is she still at Em’s house, leaving wet towels all over the place? Is Ashley Marin headed to the slammer? Whatever happens, we know Hanna is in for a rocky ride in Season 4 and we’re glad Emily seems to have her back.

Are you hoping for some quality Team Hannily time in Season 4? Would you be as cheery as Shay and Ash that late at night?! Let us know in the comments below!

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