Lea Michele still holds on to the memory of Cory Monteith through a new song that will be on her upcoming solo album.

The 27-year-old Glee star continues to build her strength after the death of her boyfriend/co-star and even tattooed the song, If You Say So on her ribcage. (See a close-up pic here:)

In the December issue of Elle, the 27-year-old actress talked about how tough it was going back into the studio to finish her solo album. She began recording back in October 2012, but after Monteith's tragic death, she decided pushing back the release date to add a song for him was the the best thing.

"The album was done, and the label said, 'Do you want to add anything?" she told Elle magazine. While she went back and forth with the decision, she ultimately decided she wanted to have a song for Cory. "I was like, 'I might regret it if I don't.'"

The song, If You Say So, was the final words Monteith said to her. She tapped Australian songwriter Sia, who co-wrote David Guetta's hit-song, Titanium.

"I said [to Sia], 'I feel like I'm starting to just sink in it, and he would never want me to do that," she told the magazine. "I need to remember that you have to live, because you can want to die.'"

She also decided to add a track called, You're Mine, which she said makes her "think so much of Cory."

"It was ours," she said of the song. "When I think of him, I play this."
