The strangest part of the post is the outdated photo used featuring her ex boyfriend Justin Timberlake which led fans online to believe Britney herself did not post it.
Happy belated birthday to this beautiful soul 🎂🎂🎂 !!! I love you so much and damn it I wish I was as smart as you at 30 !!!! It's weird to say that I was basically your momma when you were younger and yes I'm still older but your soul is and always has been wise !!!! pic.twitter.com/8qnr6l1TjD— Britney Spears (@britneyspears) April 9, 2021
I was extremely taken back and still am to this very day !!! We play wrestled at home (such classy Southern chicks) 🐣🙄😹🤷🏼♀️🤷🏼♀️ and you put me to the floor in literally two seconds after I gave all my might 😜😜😜😹😹😹 … I’ll never forget it !!!— Britney Spears (@britneyspears) April 9, 2021

For those not familiar, I've attached a Twitter thread explain who Cassie is and why fans don't believe Britney is behind her social media posts. A very good thread with receipts.
1 + 2 + 3 + bonus tweet
I don't think Britney would personally use a photo with her toxic ex-boyfriend to give her sister a birthday greeting. ONTD, I'm not being a conspiracist I promise. I just hate how her brand uses her social media.
