If you want a party done right, call Taylor Swift.

Whether it be a fan's bridal shower or a birthday for her very best friend, the number one rule for a Taylor Swift party is go big or go home.

For Swift's high school friend Abigail Anderson's 25th birthday, the pop star went all out by arranging for Dashboard Confessional singer Chris Carrabba to make an appearance at the party for a sing-a-long.

It's hard to hate, hate, hate T-Swift when she's this sweet.
