'Glee' beauty Lea Michele has paid tribute to her former co-star and boyfriend Cory Monteith on what would have been the late star's 32nd birthday. 

Writing on her official Twitter page late last night (May 11), Michele revealed that she was thinking fondly of Monteith on what would have been his birthday and she also shared an adorable yet heartbreaking picture of them smiling together:

"The biggest heart and most beautiful smile.. In all of our hearts.. We love you so. Happy Birthday."

He tragically died last year following a heroin and alcohol overdose, and Michele recently thanked her cast and crew on the 'Glee' set for being so supportive throughout such an incredibly hard time: "Last day of #Glee season 5.. I can't believe how fast this season went by.. I could not have gotten through this year... without all of you & you're endless love & support. I'm so grateful for my cast. They are my family & have held me up through everything..."

During an interview with Seventeen magazine, Michele opened up about Monteith's addiction and explained that it simply took control over him:

“I only have happy memories of Cory. He was not his addiction – unfortunately, it won. But that wasn’t who he was. Cory made me feel like a queen every day. From the minute he said, ‘I’m your boyfriend,’ I loved every day, and I thank him for being the best boyfriend and making me feel so beautiful.”
