If you didn't know that Rumer Willis was the daughter of actress Demi Moore, this photo should clear your confusion right up, while also simultaneously replacing that confusion with a whole other kind of confusion: The one where you have to stare for awhile before you can tell the two apart.

Honestly, that is uncanny.

The pic, posted to Instagram, confirms that Rumer has definitely grown up to look like her famous mom, even when the two of them aren't intentionally trying to freak us out by wearing identical jumpsuits, specs, and hairstyles.

But Rumer isn't the only one who bears a striking family resemblance to a celeb parent. Below, we round up tk more people who inherited their screen-ready features direct from Mom or Dad.

Shiloh Jolie-Pitt

Thanks to Shiloh's recent appearance at the premiere of her mom's movie, "Unbroken," we know that she's inherited both Angelina's striking features and her ability to rock menswear like a boss. (You can see the resemblance most strongly in comparison to a pic of young Angie, above.)

Willow Smith

Both the Smith kids look a lot like their dad, but Willow could literally be a young Will with the addition of nothing but a mustache.

Eva Amurri

Susan Sarandon's daughter is taller than she is, but still bears a striking resemblance to Mom.

Colin Hanks

Separated at Emily Blunt/birth?

Alexander Skarsgård

Alexander's father, Stellan Skarsgård, is probably best known for his role as the slightly dork and often nude Dr. Erik Selvig in "The Avengers" and "Thor" franchises -- but this snapshot from his early days on Swedish television, in which he could be Alexander's twin, makes it clear that mega-hotness definitely runs in this family.

Mamie Gummer

Meryl Streep's daughter could not more obviously be Meryl Streep's daughter.

Jake Busey

The "Justified" actor shares his famous father Garey Busey's hairline, and gumline. (They almost never smile in photos together, proably because the reflective glare off two Busey grins would be powerful enough to incinerate anyone within a 10-foot radius.)

Zoe Kravitz

She might have her dad's last name, but she's got mom Lisa Bonet's bone structure.

Mariska Hargitay

The SVU star is the daughter of Hollywood legend Jayne Mansfield, and yep, you can definitely tell.

Scott Caan

Like father (James Caan), like son.

Scott Eastwood

Scott definitely inherited father Clint's chiseled features, although the jury is still out on whether he also shares his dad's penchant for arguing with empty chairs.

Emma Roberts

Although Emma is the niece, not daughter, of star Julia Roberts, you can definitely see which side of the family she got her smile from.

Ethan Peck

And although Ethan is the grandson, not the son, of classic film star Gregory Peck, let's just say that granddad's seed of iconic good looks is, ahem, still going strong.
