The actress was joined by family members and friends as she unveiled the 2,505th star on the famous sidewalk.
Glee creator/producer Ryan Murphy, who was there to salute his leading lady, told the crowd, "She is the hardest-working person on the set... She makes everybody better and everybody happier. She is one of the comedy greats in our business - a true class act."
The proud star, who plays Glee's mean cheerleading coach Sue Sylvester, shared photos of her new plaque with fans on Twitter.com, writing, "Here she is. Mind blown."
