There's no shame in Rachel Bloom's Golden Globes preparation game.
The Crazy Ex-Girlfriend star is nominated for Best Performance by an Actress in a Limited Series or Motion Picture Made for Television, and while getting ready for the big night, she put on a show on for her Instagram followers.
Donning only a pair of Spanx and a corset, Bloom did a little dance while singing her "Sexy Golden Globey Song."

At the end of her performance, the 28-year-old actress admitted, "I can't breathe."
Bloom wasn't the only Golden Globes nominee to post a silly video ahead of hitting the red carpet. Spotlight actor Mark Ruffalo also revealed that he had just started to write an acceptance speech in the off chance that he wins. "Trying to think of what to say," he quipped.

This is Ruffalo's second Golden Globe nomination, and Bloom's first. She will go up against Jamie Lee Curtis (Scream Queens), Julia Louis-Dreyfus (Veep), Gina Rodriguez (Jane the Virgin) and Lily Tomlin (Grace and Frankie).
ET spoke with Bloom prior to her musical debut on television, and she revealed the craziest thing she's ever done for love. Check it out:
