But it looks like her feelings run deeper than we could have ever imagined.
The actress just revealed another tattoo dedicated to Cory's "Glee" character, Finn Hudson.
The "Finn" ink was brought to light when Lea stripped down for a naked photoshoot for Women's Health magazine.
She posted the front cover on Twitter and mentioned how proud she was to be following in the footsteps of Chrissy Teigen.

Earlier this year she broke our hearts with a powerful tribute to Corey on Twitter.
She honored his life in the most beautiful way. It's a picture of Cory on a beach with the words,
I know everyday you're watching over me, and smiling. Love and miss you Cory, everyday, but today a little more.
Her heart-wrenching tribute has been shared more than 60,000 times.
Thousands of people, including Cory's former co-stars, were honoring his life with the hashtag #3YearsWithoutCory back in July.
