Woman's cat has bizarre reaction whenever she sings: 'Oh really, Helen?'

Tough crowd.

A singing woman named Liz, who says her cat, Helen, owns her — not the other way around — is going viral, but not for the reason you may think.

Instead of wowing the internet with her incredible vocals, Liz has made a hobby out of capturing her cat's rather critical reactions to her singing voice.

The pet owner has shared dozens of videos of herself on Instagram, belting out popular tunes, such as the Beach Boys' "Wouldn't It Be Nice?" and even "Smelly Cat" from the hit show Friends — all of which are not well-received by the tuxedo cat.

Just seconds after Liz opens her mouth in each short clip, Helen can be seen "attacking" her, jumping on her head and halting her performance for good.

“Wouldn’t it be nice if she could shut up?” Liz captioned one of her comical posts.

The cat and owner duo, known as "Oh really, Helen?" on social media, has amassed over 63,000 followers on Instagram through their shenanigans.

And though Helen may seem like a vicious critic, her owner assures she has not been hurt in the making of any videos.

Still, she's definitely not a fan.
