What’s a girl to do when her birthday lands on a Monday and she’s too busy at work on Glee to really celebrate? Throw a huge, unforgettable party over the weekend, of course!

Glee’s Dianna Agron (Quinn) turns 26 years old today, April 30, but the cheerful star has already celebrated in style. On Sunday, Dianna hosted a fun and quirky circus-themed bash to celebrate her big 2-6.

Along with co-stars Grant Gustin (Sebastian) and Kevin McHale (Artie), who tweeted photos in matching creepy clown attire, Dianna also celebrated with another famous pal: country music singer Taylor Swift.

Twitter is full of cute photos of Dianna and Taylor’s real-life friendship, and Di’s even blown kisses to her pal on national television, so her invite to Dianna’s party really comes as no surprise.

Taylor donned cat ears and a cute tiger costume for the big bash, while Dianna wore a circus leotard and a sassy pink feather — all while snacking on tasty cotton candy during pics. “The most magical night at @DiannaAgron's circus themed birthday party!” Taylor tweeted that night.

The next day, Dianna wrote, “Can't believe all this Birthday love. Mind reeling. Had the most magical weekend, celebrating with the most loving & generous friends.”
