Dianna Agron Birthday: Taylor Swift Tweets Photo From Birthday Bash

Life's a circus for Taylor Swift and new bestie Dianna Agron. The "Sparks Fly" singer tweeted a photograph of the "Glee" star and two of their gal pals at Agron's carnival-themed birthday bash over the weekend, which meant that feathers, fringe, bowler caps and tiger stripes were out full force.

It's been a busy week for the blond BFFs. Agron, who turns 26 today, and Swift, 22, also celebrated Shirley MacLaine's 78th birthday earlier last week by dressing up "full-time fancy" (flower headwear, elbow-length gloves) and dining out in honor of the legendary actress.
