Do you know which of these actresses stars in Jurassic World?

YOU’RE WRONG. Jessica Chastain is not the star of Jurassic World. Bryce DallasHoward, however, is. Thank you very much. Recently, Chastain took to social media to alert the world:

We know what you’re thinking: “Ugh, obviously I know the difference between Jessica Chastain and Bryce Dallas Howard. Chastain was in The Help and Dallas Howard was in The Help-- oh wait.”

Or maybe you actually do know. But it appears that a lot of people — more than we expected, to be honest. C’mon guys, did you also think that was Chastain in Spider-Man 3? — had no idea that Jessica Chastain isn’t in Jurassic World:

No, it’s not. But we understand your confusion:

And no, it doesn’t appear that “Jessica Chastain” is a performance art piece by Bryce Dallas Howard either. Chastain followed up her previous Insta with this Dubsmash video today of Bryce Dallas Howard — the real Bryce Dallas Howard — singing a particularly apt tune:

It’s a soundbite from “Jessica Chastain: The Musical,” with singer Stephanie Koenig performing the Bryce Dallas part. Another choice lyric: “I’m the one from Lady in the Water / For Christ’s sake I am Ron Howard's daughter / So behold this sad refrain / I am not Jessica Chastain.” Watch the whole thing for an LOL:

So now you have been properly schooled. But don’t be embarrassed. Don’t be ashamed. It’s a common mistake, and one that both ladies want to use to their benefit, judging by tweets by Chastain:

“When we did The Help together, the first thing that we did was we beelined for a mirror,” Bryce also told E! News. “And we were like, ‘OK so we both have a cleft chin. Our noses go up. Our [eye] placement is similar.’ I’m like, ‘Jess, you’re way more chiseled. You have big, luscious lips.’ ... I feel so lucky that people still feel like I look like her. Because honestly, I feel like she’s the most beautiful person on planet Earth.”

Humblebrag much. Anyway, maybe just cast Chastain in Jurassic World 2: Jurassic Universe and confuse the heck out of everyone.
