The 'Glee' actress said she will always love and miss her late boyfriend and co-star, who was found dead in his hotel room in Vancouver, Canada on July 13, 2013 from a heroin and alcohol overdose at age 31.
The 27-year-old actress posted an old photograph of the Canadian actor, in which he is smiling on a beach, on Twitter, and wrote: ''We hold you in our hearts today, and every day we remember your smile. We will love you and miss you always.''
A source close to the brunette beauty, who recently started dating Matthew Paetz, told gossip website HollywoodLife.com: ''She is going to mourn on her own time and keep her thoughts and feelings to herself.
''She knows that Cory would want to live her life and that is exactly what she will be doing.''
Lea's co-stars also remembered Cory on their social media profiles.
Matthew Morrison tweeted: ''I personally believe Cory was reborn into some other beautiful form a year ago today. I celebrate him and his life... Wherever that may be.''
'Glee' creator Ryan Murphy simply tweeted: ''Miss you.''
Actor Kevin McHale posted: ''It's been 1 whole year & it's still so surreal, but today is just a reminder of how damn great you were and how much you mean to us all''
While Harry Shum Jr. tweeted: ''I often think of the good memories I shared with Cory and it makes me smile. He was a one of a kind gentleman and will forever be missed.''
