Lea Michele's keeping an eye out for grumpy Gleeks.

After Tuesday night's episode of the quirky FOX comedy brought an end to fan-favorite couple Rachel and Finn (portrayed by Michele and Cory Monteith) the star, 24, has had some explaining to do.

"Fans are pissed!" she told Thursday as she was honored at Billboard's Fifth Annual Women in Music event. "I went up to [creator] Ryan [Murphy] and said, 'How could you do this?!' But I think if they're meant to be together, they will."

As for her character's dalliance with bad boy Puck (Mark Salling) which ultimately led to the breakup, Michele hints the pair could lock lips again: "We'll have to find out!"

The other hot topic at the forefront of the Broadway star's mind? The show's two Grammy nominations, including one for Best Pop Performance by a Duo or Group for their cover of Journey's "Don't Stop Believin'."

"Gosh, it's so awesome -- I can't wait," she told Us, adding that "it doesn't feel real yet."

And though she just heard of the nods Thursday morning, prep work is underway. Said Michele, "I've already started thinking about what I'm going to wear!"
