64715Today is Dianna Agron's 29th birthday and her former Glee co-stars have been sending her all the love! Jenna Ushkowitz and Kevin McHale both posted cute wishes on Twitter and Instagram earlier today and shared the best photos. Jenna wrote, "Happiest of Birthdays to my baby bunny. The most beautiful, adventurous and loving girl I know. I love laughing with you. Thank you for always being the best friend a bunny could have. LOVE YOU @diannaagron"Kevin took a more comical route and shared a pic of Dianna sleeping with the caption, "Happy birthday to this sleeping beauty (literally can fall asleep anywhere) @DiannaAgron!! Can't wait to see ur play!"
