Lea Michele is days away from making her debut in “Funny Girl” on Broadway.

And given that she will be THE ‘funny girl’ it means all eyes, headlines and phone cameras will be on her waiting for her to mess up.

Lea doesn’t have the best track record of good behavior on set.

When she was on “Glee” was known as the mean girl on set and many called her a ‘DIVA.’

In a new interview with The New York Times, Lea, “I have an edge to me. I work really hard.”

“I leave no room for mistakes,” the 36-year-old said.

She explained this work ethic led to “blind spots.”

“That level of perfectionism, or that pressure of perfectionism, left me with a lot of blind spots.”

Lea noted that she’s changed the way she approaches her work given her past “mean girl” reputation
