Taylor Swift loves her friends. So when she wanted to celebrate her childhood best friend Abigail Anderson's birthday, she wanted to do it right.

The "Style" singer just posted some pics from the Nashville festivities on Instagram. Done photo booth style, the picture above not only shows how much love she has for her bestie but also how far their friendship has come. Taylor and Abigail have been friends since 2005. And no matter how famous Taylor became, she made sure to have Abigail by her side. Taylor even took her as her date to this year's Grammy Awards!

"'Hands down this is the best day I can ever remember. I'll always remember.' @taylorswift," Abigail captioned the same Instagram photo from that night.

The other images show who else came to the celebration. In one photo, the two are posing with Paramore frontwoman Hayley Williams, who's rocking some periwinkle glasses and a magenta wig. In another photo, Taylor is striking poses with Abigail, country singer Kelsea Ballerini and some other friends.

Her final post from the party features Taylor wearing a pair of dollar sign glasses and a crown with her brother Austin, Victoria Secret model Lily Aldridge and two members of Kings of Leon -- Caleb (who's Lily's husband) and Jared Followill. "Nashville Squad featuring 4 Followills and 2 Swifts," she wrote in the caption shouting out Austin, Caleb, Lily, Jared and his wife, Martha.

There aren't many other details about the party, but the photos prove that it was a lot of fun. See the rest of her Instagram party pics below.
