Justin Bieber and Hailey Baldwin seen on the streets of Brooklyn on Sept. 14, 2018 in New York City.

Hailey Bieber isn't having it. The model came to husband Justin Bieber's defense on Monday (July 15) three days after Tool singer Maynard James Keenan referred to Justin's fandom of the doom rock band's music as "#bummer." The comment came a day after Bieber shared some lyrics from Tool's 2006 song "The Pot" on his Instagram story.

Well, Hailey had some stern words for the Keenan in response. "He expressed he was a fan of your music," she tweeted. "Grew up listening to your music. You must be unhappy with yourself that you want to make people feel small who express their admiration for you. Very childish and hurtful thing to do. I hope u find security within yourself. Sad place to be."
