Today is undoubtedly a tough one for Cory Monteith's (Finn) loved ones and fans, as the late Glee actor would have celebrated his 32nd birthday today. Lea Michele (Rachel) remembered Cory on his birthday by tweeting a cute pic of the couple together and including a very sentimental message.

On May 11, Lea posted a throwback pic (at left) of herself and Cory sharing a laugh. "The biggest heart and most beautiful smile," Lea tweeted. "In all of our hearts.. We love you so. Happy Birthday."

It's tough not to get emotional while reading Lea's message, and it reminds us all of how great they really were together. And we agree with Lea that Cory's smile was truly infectious. 

It's hard to believe that it's almost been a full year since Cory passed away from a drug overdose on July 13, 2013. Glee has paid tribute to his memory throughout Season 5, including Season 5, Episode 3's memorial episode. More recently, New Directions performed all of Finn's favorite songs at Nationals. 

Lea has found many ways to memorialize Cory herself, including writing a song about their relationship for her album, along with getting a tattoo on her ribcage of his final words to her.
