Taylor Swift is getting support from a childhood bestie.

Abigail Anderson – the subject of Swift’s 2008 “Fifteen” – took to Instagram on Wednesday to give her pal a sweet shout-out after the singer’s split from Calvin Harris.

In the photo, Anderson holds a small note card with the words “My weird heart loves your weird heart.”

Anderson included a thankful caption with the post.

“There are few things more significant or valuable than a friendship that will withstand the test of time,” she wrote. “Thank you for getting me. Always. @taylorswift.”

The post came on the same day that multiple sources confirmed exclusively to PEOPLE that the 26-year-old singer and the Scottish deejay, 32, broke up after 15 months together.

An insider told PEOPLE that “no one cheated.”

“There was no drama,” the source said. “Things just don t work out sometimes.”

The breakup comes less than three months after the pair celebrated their one-year anniversary with a tropical getaway.
