73rd Annual Golden Globe Awards: All the Red Carpet Stunners!

Rachel Bloom looked gorgeous in green when she hit the red carpet at the Golden Globe Awards on Sunday night -- but a pic she posted online beforehand proved her prep for the main event was anything but glamorous.

The "Crazy Ex-Girlfriend" star, who picked up a trophy for her work on the CW show last night, wore a form-fitting Christian Siriano gown, but getting into it wasn't easy.

In a video uploaded to the 28-year-old's Instagram page hours before the show, Bloom is seen getting ready for the night, wearing only a pair of Spanx and a corset. In the clip, she sings "The Sexy Golden Globey Song," a short ditty that ends with her exclaiming, "I can't breathe!"

It's the Sexy Golden Globey Song.

"[The dress] was designed for me by Christian Siriano, and what I love about it is that it emphasizes the parts of my body that I'm very proud of," the actress told Us Magazine about her look. "I'm wearing old-school undergarments under this. I'm wearing, like, two corsets! But it emphasizes the curves, and I don't feel like I have to be sucking in my stomach for three-and-a-half hours to pull off a sheath dress."

We gotta applaud her honesty and her big win!
