Taylor Swift shared a sweet birthday message for her brother Austin on Friday (11Mar16), posting a throwback photo of the pair during a family photoshoot.

"HAPPY BIRTHDAY AUSTIN!!!!!" Taylor captioned the picture on Instagram.com of the siblings dressed in typical 90s fashion, throwing their heads back with laughter. "Thanks for 24 years of LOLs (laugh out louds). @austinkingsleyswift."

The Shake It Off hitmaker has never been shy in showing support for her family, especially her little brother. When the 24-year-old made his acting debut in the thriller I.T., she took to Instagram again to tell her fans just how proud she was.
"My brother @austinkingsleyswift just acted in his first movie and I'm all proud and stuff," she wrote in September last year (15).

The support is most definitely mutual too, with Austin stepping up to defend his famous sister earlier this year (16) after Kanye West referenced Taylor in a track on his new album, The Life of Pablo.

During the launch of Kanye's new fashion collection and album in February, the rapper's track Famous was revealed to have a controversial line in about the pop star.

"I feel like me and Taylor might still have sex," Kanye raps. "I made that b**ch famous."

Posting a video of him putting his Yeezy sneakers - designed by the rapper - in the trash, Austin wrote alongside the footage, "Here we go again" - a reference to Taylor and Kanye's previous falling out after the rapper stormed the stage during her acceptance speech at the 2009 MTV Video Music Awards.

Taylor, who was collecting the Best Female Video Award for You Belong To Me, was left humiliated as Kanye snatched the microphone from her hands and told the audience that the honour should have gone to Beyonce for Single Ladies.
"Yo Taylor. I'm really happy for you, I'm going to let you finish, but Beyonce had one of the best videos of all time," said the rapper.
