A photo taken at the Saturday, April 28 party shows the 'Sparks Fly' singer rocking a seductive tiger-inspired costume, and the 'Glee' actress donning a trapeze artist get-up.
Dianna Agron has celebrated her 26th birthday early. The Quinn Fabray of "Glee", who turns a year older on Monday, April 30, threw a circus-themed party this past Saturday, and her best friend Taylor Swift treated fans with a sneak peek from the bash by posting an Instagram photo on her Twitter page.
Made up of two snapshots, the image captures the two blond beauties posing in costumes with some of their girl friends. While Swift chose to don a sexy tiger-inspired costume, birthday girl Agron put on a trapeze artist get-up. In the caption of the picture, the country music crooner wrote, "The most magical night at @DiannaAgron's circus themed birthday party!"
This isn't the first time Agron and Swift play dress-up for a birthday celebration. Four days earlier, the twosome shared on Twitter photos from their special dinner in honor of Shirley MacLaine's 78th birthday. The pictures display the two stars and their friends posing in vintage pastel dress, gloves and flower crown.
As for Agron's birthday bash, it was also attended by the actress' co-star Kevin McHale. The 23-year-old actor posted on Saturday a before-and-after photo of him with a clown make-up. The next day, he once again took to Twitter to write, "@taylorswift13 @diannaagron face. Melted. Best bday party evaaa :)"
