Taylor Swift's BFF has her back.

On the same day news broke that the 26-year-old singer and her boyfriend of over a year, 32-year-old DJ/producer Calvin Harris, have split, Swift's childhood bestie took to Instagram to share a sweet message dedicated to her.

"There are few things more significant or valuable than a friendship that will withstand the test of time," Abigail Anderson, who's been best buds with Swift since high school, captioned a picture of a card reading "My weird heart loves your weird heart" on Wednesday.

"Thank you for getting me. Always. @taylorswift," she added.

Anderson and Swift have stayed close through the years despite the "Shake It Off" singer's superstar status and busy schedule. Anderson served as Swift's date to the 2015 GRAMMYs, and Swift adorably arranged a surprise performance by Dashboard Confessional's lead singer, Chris Carrabba, for Anderson's 25th birthday.

And Swifties are already showing their support for the GRAMMY-winner after her breakup through Anderson.

"Please give Taylor a hug from all of us," one comment on Anderson's post reads.

"Please take care of my Queen so much... & please tell her we all love & support her unconditionally & we believe that she deserves all the best so there's no need to worry, cause life will prepare so much better for her!" another comment reads. "If her heart is broken, Swifties' hearts will break too!"
