Lea Michele offered an apology Wednesday after a former Glee co-star made pointed accusations about her behind-the-scenes behavior.

In a lengthy note posted to Instagram, the actor and singer acknowledged that she clearly acted in ways that hurt other people, but said she didnt recall a specific incident cited by Samantha Marie Ware on Twitter.

Whether it was my privileged position and perspective that caused me to be perceived as insensitive or inappropriate at times or whether it was just my immaturity and me just being unnecessarily difficult, I apologize for my behavior and any pain which I have caused, she wrote. We all can grow and change and I have definitely used these past several months to reflect on my own shortcomings.
