If you follow Hilary Duff on Instagram (who doesn't?) then a certain post might have had you thinking: Is Hilary Duff pregnant? The 30-year-old actress recently posted an adorable boomerang showing off her fave spectacles from her new Glasses USA collab — and fans quickly noticed what appears to be a baby bump! But, before you pop the bubbly and start guessing the gender (she needs a daughter!) you might want to read her caption first…

"Of course my faves are the “Lizzie” also not really pregnant guys….just shooting a movie ☺️ @glassesusa muse x Hilaryduff which are your faves???? Tell me tell me now!" Okay, talk about a BUMMER. Hilz, we all think that Luca needs a little sibling and considering you're like a perf mama you really had our hopes up for a second. But let's not get too disappointed because the star did drop a pretty big clue about her next exciting project!

A post shared by Hilary Duff (@hilaryduff) on

After doing some digging we discovered that according to Refinery 29, Hilary is in the process of filming The Haunting of Sharon Tate. Twitter account Hilary Duff News also tweeted, "CONFIRMED: @HilaryDuff is set to star in The Haunting of Sharon Tate based on the popular Manson Murders story, an adaption by Daniel Farrands. Hilary will be starring in the leading role of American actress and model Sharon Tate, who was murdered by Charles Manson."

Okay, so yes, this happy "Hilz might be preggers" article has taken a slightly haunted turn… BUT this is awesome news for the talented actress. And, just to clarify the late actress, Sharon Tate wasn't actually murdered by Manson — she was killed by his followers. Alongside the Younger star, Jonathan Bennett — aka Aaron Samuels from Mean Girls — will also star in the film, so it's bound to be legendary. Let's just hope he wears his hair pushed back.
