‘Crazy Ex-Girlfriend’ star breaks down that pitch perfect Beyonce-esque opening number

Crazy Ex-Girlfriend started with a bang.

Or, more accurately, the second season of the cult fave began moments after said backseat bang between Rebecca (Golden Globe winner Rachel Bloom) and Josh (Vincent Rodriguez III), following her revelation that actually, funny story, she did move across the country for him. No big deal!

Thanks to a little table-turning, Rebecca is able to talk Josh into not caring so much about that inconveniently timed personal revelation, and the premiere finds that the two have subsequently slid right into a no-strings-attached casual thing, with Josh crashing on her couch and Rebecca plotting a happily ever after once again.

The stellar first episode back also finds perennial sidekick Paula (Donna Lynne Champlin) emerging from Rebecca's shadow and exploring her own legal career options. The gang also must deal with the sobering revelation that post-wedding blackout Greg (Santino Fontana) is MIA and in AA -- and none the wiser about Rebecca and Josh.

Mashable spoke to Bloom by phone earlier Friday for her take on that catchy new theme song, what's next for Paula, and why the show will soon start channeling Breaking Bad.

We kick off the show with a new theme song. How did that came about? Every season that we’re going to do has a different theme and a different point of view. It’s almost like we’re re-starting a new show in some ways. So the last theme song was all about denial: "I just happen to be here; it’s not cause Josh is here." This theme song is: I’m in love! I’m just a girl in love and this is what you do when you’re in love, you crazy minx. And what do you think Rebecca’s goal or overall theme is this season? Love solves all your problems and you should do anything to get it and keep it! The first big number this season is the Beyonce-esque "Love Kernels." When a song like that happens on the show, what comes first: Is the story happening first, or do you begin with the song topic or genre idea? Usually story comes first but [co-creator Aline Brosh McKenna] and I had kind of known before we wrote the episode what this song would be. "Love Kernels" is in many ways our "West Covina" song this season. It’s our big song in our first episode thematically stating what’s going on, and so even before we started to write the episode I started to percolate on this song and what it would be. So this song came before other songs normally do. We didn’t have to write the episode first to know there would be a place for it. As you get further into the season and stuff becomes a little bit more of a question mark as we’re going into individual episodes, you have to wait [a bit before] you settle on the songs. Where do you want to see Rebecca go this season? We’re filming episode nine right now and we just finished outlining the season finale so I’m excited for her to continue on this path that we’ve had planned out for the last three years which is fully exploring the premise "Crazy Ex-Girlfriend." What does that mean? [I want to see] her slowly work her way to happiness even if it’s her first taking two or three or a thousand steps back. Do you have a future scene or situation that is kind of your dream to see Rebecca in? Well, the show we kind of idolize the most with this show is Breaking Bad. And it might not seem like the two have a lot in common, but I’m really excited to get to the part where you see why the two have a lot in common.

One of the highlights of the premiere is the Rebecca/Josh number “We Should Definitely Not Have Sex Right Now.” Such a great club song for so many characters’ lives. Can you take me through the genesis of that tune? Yeah, we had a whole other song we were going to do but it just didn’t seem right. And then Aline came into this office one day and said, “What if we did a song between Rebecca and Josh that was just like, “We should definitely not have sex right now.” And we were like, ‘Done!” So Jack [Dolgen] and I wrote that up in about 10 minutes. It's one of those songs that once you had the title, it really wrote itself. [laughs] The premiere showed Paula has decided to no longer participate in Rebecca’s schemes and shenanigans. All Season 1 she was the sidekick, a best friend, just helping the protagonist along. And we want to look at that stereotype and realize she has her own hopes and her own dreams and realize that she herself would be a fantastic lawyer. So it was really important to us to really round out the character of Paula in Season 2. We see in the premiere that Greg is in AA now. What does their relationship look like going forward now that Rebecca is aware of that fact? If you look at the show, everyone is on the road to happiness, which is what the show is about. Greg went from the character that was probably furthest from understanding what his happiness was to now making leaps and bounds [towards it]. And so, with Rebecca being on the same emotional level of what they want in their lives, he’s about to [now] really take giant leaps [ahead] of her. And so there’s tension from that. I can’t let you go without asking about White Josh and Darryl. The fan response to that relationship has been so exciting, and in the premiere they appear to be blissfully happy. Were you surprised by the reaction to them, and what’s the plan going forward? I didn’t see it coming, but I was there on set when they shot their first kiss and I was like, ‘Oh, this is instantly my favorite couple on the show.' So I’m just happy fans feel what I feel. And they are, at the end of the day, in a pretty good relationship. So there’s not, our story is all about conflict, so conflict between them doesn’t come up for a little bit, but we do our best to touch on them and show they are in a relationship that’s progressing and it is really healthy and happy. You mentioned that you have everything sort of sketched out with respect to Rebecca’s journey. I don’t want to say "happily ever after" because that's the antithesis of this show, but can you tease thematically what the end looks like for her? Well, all I can say is we know the final moment so specifically. The show is about happiness. It’s about love, obviously, or what we think love is, or what it might be but it’s also about [the fact] we all pursue happiness. The second Rebecca is happy, the show ends. The show also ends if she dies! So...yeah.
