A few months ago, Mulligan, 25, told Vogue that despite her interest, she was considered "not famous enough to be a cameo yet" on the award-winning show. But series creator and producer Ryan Murphy says he would have her on his program without thinking twice.
"I thought [her comment] was sort of funny because I love her, and I would definitely 100 percent put her on the show," Murphy told PEOPLE Sunday at the Golden Globes, where Glee was named best comedy or musical for the second straight year.
In fact, Murphy, 45, recently confronted the Wall Street actress about the matter.
"I actually saw her not too long ago, and I said, 'You're famous enough,' " Murphy explains. "She blushed. She's very sweet."
But unlike the case with Anne Hathaway, a deal to appear on the show wasn't made on the spot.
"We're not writing anything for her [right now] because I think she is busy with a couple of projects," Murphy says. "But I do love her."
