Despite her massive success, Lea Michele continues to pay credit where it is due and that means giving major props to her dead boyfriend Cory Monteith.

The "Glee" season 5 star recently admitted that the late actor had a hand in shaping her memoir, "Brunette Ambition" before he passed away last July.

According to Us Weekly, the 27-year-old opened up about the processing of writing her first book, especially when it came to talking about her best friend Jonathan Groff.

During a book book signing Q&A on Wednesday, May 21st, at Barnes & Noble Union Square in NYC the Fox star explained Monteith's urge for her to be sensitive about her pal's story.

She admitted to Groff, "I did write a lot in the book about you coming out to me," adding, "and what that was like." The actor who was a "Glee" guest star came out publicly in 2009, revealing that he was "gay and proud."

Lea Michele continued, "I remember Cory telling me when he read the book, 'You have to be... You've got to be careful because you're talking about someone.'" Taking his advice into account the Bronx native confessed she "edited down that chapter a lot."

The "Louder" artist said, "I think when you're writing a book, it's very important to think about the people [you're] talking about," adding, "I really wanted to talk about everyone a lot."

The "Cannonball" singer admitted that she strayed away from her nature of wanting to divulge secrets and instead played coy when asked about her "Glee" costars. Michele explained, "You have to take into consideration: How will I affect them?"

She continued, "A little regret if anything," adding, "I do wish I could have gotten a little bit deeper in the Glee chapter... there's so much that I wanted to talk about it."

Lea Michele admitted that the chapter in General was a hard one to write. She said, "There was so much," adding, "To put into words what the past 6 years has been like -- on a show -- was really hard. It's been hard for me to explain what these experiences were like [and to put them] into words."

In the dedication segment of her first book the actress thanked Cory Monteith for being her biggest fan. Michele confessed, "Maybe years down the road, I'll be able to really, really say what it meant to me," adding, "It is very hard to comment on the experience."

She explained, "I mean, I'm 27, so I think I've got some time for that."
