Rachel Bloom's new show, Crazy Ex-Girlfriend, unveils the extent to which some women will go in order to get the attention of a crush, and the 28-year-old actress told ET why she's not beyond some of the tactics her character employs.

"The craziest thing I did for love was the ways I tricked myself into thinking I wasn't stalking someone," Bloom shared. "I would go to a place just to run into them, and I have this in my diary. I'd be like, 'Dear diary, today I went to this Starbucks just because I wanted to go there, and I happened to run into blah blah blah."

In the highly anticipated comedy, Bloom is Rebecca Bunch, a successful Manhattan attorney, who turns into a "crazy ex-girlfriend" when she follows a former fling, played by Vincent Rodriguez III, across country to a suburb of Los Angeles.

Bloom came to fame five years ago via her viral YouTube music video in which she professes her love for Ray Bradbury in no uncertain, NSFW terms. Crazy Ex-Girlfriend also has a musical element to it, as Broadway-trained co-star Donna Lynne Champlin, who plays Bloom's BFF in the show, explained to ET.

"Somebody's having a scene and then all of a sudden in my mind or whoever's mind it turns into a musical number," Champlin said.

While we've seen musical shows before (e.g. Glee, Smash, Galavant), Crazy Ex-Girlfriend is different in a way that Bloom explained to us through a simple comparison.

"I describe it as Ally McBeal meets Flight of the Conchords," Bloom said. "That's the closest approximation."

Crazy Ex-Girlfriend premieres Monday at 8 p.m. ET/PT on The CW.
