It’s getting harder for Stephen Colbert to repress his inner musical urges. After recently dueting with Anna Kendrick and Tom Hiddleston, the Late Show host got another huge opportunity to show off his pipes when Crazy Ex-Girlfriend co-creator and star Rachel Bloom stopped by Tuesday’s show.

Colbert began by asking Bloom, in his standard interview style, about how one integrates musical tropes into telling a story. After all, that’s not how real life works. Bloom responded, “Anything can be a musical,” prompting the two to launch into a new musical number of the same name.

“Musicals don’t just happen when you’re talking to a guest / There’s no Broadway razzle-dazzle, you’re just gabbing at some desk,” Colbert sang.

“I see what you mean, but it’s time to break the routine,” Bloom replied.

“But Rachel, what about feeding the publicity machine?”

Colbert sang-asked for stories from the set, so Bloom responded by rapping, Music Man-style: “There’s so much food around the set that I can’t help but go nuts eating cheese and crackers, party mix and donuts / Being a star ain’t as sexy as it sounds, I won a Golden Globe but I put on 13 pounds!”
