The Secret Is Out: Millie Bobby Brown hates Will's haircut

"Stranger Things" co-stars Millie Bobby Brown and Noah Schnapp are EXTREMELY close friends.  But love has its limits.  And one of those limits is the ridiculous bowl cut Noah has to wear when he plays Will Byers on the show.

"Vanity Fair" subjected Millie to a lie detector test, and they asked her if Noah looks good with that haircut.  She said YES, and the guy administering the test determined that was a LIE.  

Check out the video here:

Millie also revealed that Finn Wolfhard is a LOUSY KISSER, but she's never told him that before.  (That happens at 5:35.)
