Happy birthday, Dianna!
Taylor shared a photo from Dianna's circus themed party and all the ladies in attendance definitely played the part.
Yep, Taylor, Dianna and friends are seen in the pic wearing circus-centric costumes to celebrate the Glee star's big day.
This isn't the first time Taylor and Dianna have gotten together to wear costumes--earlier in the week, they celebrated Shirley MacLaine's 78th birthday by dressing up.
Taylor looked adorable in a tiger outfit, while Dianna channeled her inner trapeze artist.
Taylor shared the photo, with the tweet: "The most magical night at @DiannaAgron's circus themed birthday party!"
