It's the feud everyone is talking about. The social media scandal that has rocked the world of celebrities...forever. OMG, did she really just post that? Yes, and now nothing will ever be the same.

It's Cher vs. Kate Hudson.

Who did you think we meant? The music icon and even more prominent Twitter icon took to her medium of choice on Monday to shade Fabletics, the activewear line that Hudson co-founded.

"Made mistake of going2 Fabletics.What a pain in the ass.won’t even let u see anything Till u give them ur 1st born‼" Cher tweeted, tossing in a red exclamation point emoji for good measure. "Felt I Was Being Conned"

Fabletics is -- maybe? -- a monthly subscription-based service, though we have to admit we spent a considerable amount time on the website and we're still not actually sure what you get with VIP points or what a "VIP Membership" entails.

We did find this funny paragraph about Hudson, though:

"An iconic actress, fashion tastemaker and mother of two, Kate Hudson was born to inspire others. Her passion for motivating and supporting women to lead healthy and active lives led Kate to co-found Fabletics. Each month, she shares her favorite outfits, so you can rest assured they’re always Kate-approved."

~Born to inspire others~

Anyway, the iconic actress, fashion tastemaker and mother of two has been in Ibiza for the past week and seems unbothered:
