As if Shay Mitchell couldn’t get more adorable, she recently Instagrammed a throwback pic of her as a little girl, wearing a cute Tweety Bird bathing suit and looking a bit cranky as someone snapped her picture.

“Throwwwwwbackkkk!,” she wrote as a caption. “Lol loved this lil Tweety bathing suit back then! #waterbaby #TBT.” We love her lil’ Tweety suit too. It’s always sweet to see our favorite Pretty Little Liars stars as small children (and no, we’re not talking about these Season 4 spoiler pics), and it’s crazy to see how much they’ve changed since the simpler days of childhood. Who would have thought that this little cutie in a swimsuit would go on to play the fierce and awesome Emily Fields?
