Taylor Swift Throws Best Friend a Star-Studded Party, Celebrates Easter With Her Family

— -- Taylor Swift had a busy weekend: She attended a star-studded party in Nashville on Saturday to celebrate the 25th birthday of her best friend Abigail Anderson, and followed that up with a family Easter egg hunt on Sunday.

Swift, 25, who met Anderson during their freshman year at Hendersonville High School, shared a couple of photo booth pictures on Instagram captioned, "Since '05. @abigail_lauren."

Other party guests getting in on the photo booth action included Paramore's Haley Williams and Swift's model pal Lily Aldridge. Aldridge's hubby Caleb Followill, his siblings, Jared and Nathan Followill and cousin, Matthew Followill, who make up the Nashville-based rock band, Kings of Leon, were also on hand, along with Taylor's brother, Austin.

"Nashville Squad featuring 4 Followills and 2 Swifts @lilyaldridge," the "Blank Space" singer titled a pair of pictures of the group.

Swift also surprised her friend by bringing in singer-songwriter Chris Carrabba of Dashboard Confessional to perform at the party.

On Sunday, the "Shake It Off" singer and Austin took part in a family Easter egg hunt. Swift posted a video of the two showing some unsportsmanlike conduct as they tried to gain an upper hand in the hunt.

"When your parents arrange a competitive sibling Easter egg hunt, failing to take into account that their children are Ross and Monica," the pop star wrote, referring to the rivalry between the brother and sister characters played by David Schwimmer and Courteney Cox on "Friends."

A second post showing the two gathering eggs is captioned, "I'VE GOT LIKE A HUNDRED GOOD LUCK."
