But now makeup artist Patrick Starrr has just made it a reality, and we can't believe (we can) how absolutely stunning she looks as Ariel.
PHENOMENAL.
If you didn't stan Madelaine to play Ariel in the upcoming live-action Little Mermaid, we're pretty sure you will now.
"How this has never happened before," she wrote on her own Instagram. "I don't know. But I am LIVING as Ariel🧜🏻♀️"
Yessss girl. You really are.
