Taylor Swift has already taken the title for her ultimate #squadgoals, and now she's making a play for #siblinggoals too. The pop superstar took to Instagram on Friday to wish her little brother Austin a very happy birthday with a throwback photo that really takes the (birthday) cake.
Swift wrote: "HAPPY BIRTHDAY AUSTIN!!!!! Thanks for 24 years of LOLs. @austinkingsleyswift"
We already got a glimpse at how close the two are when Austin dumped his Yeezy Boost sneakers in a gesture of solidarity with his big sis following the whole Kanye lyrics debacle last month. This just seals the deal—in the most adorable way possible.
