In anticipation of her new album, Selena Gomez reportedly wrote a new song with Charli XCX titled "Bad Girlfriend". The song is about a girl who is getting wiser after taking the blame for a failed relationship despite her boyfriend's fault. The lyrics include, "I know I'm not there for you or there when you call. I'm a bad girlfriend/ I'm a bad girlfriend."

"It's all about a boyfriend the girl is no longer really into and has finally gotten wise to. It's tongue-in-cheek and Selena and Charli knew exactly who they were writing about," an insider told The Sun. "She sings about how a good girlfriend would just carry on and let their boyfriend walk all over them, with their cheating and whatnot, but she's changed her ways."

Rumor has it, the song was inspired by Selena and Charli's past relationships with their exes. And if we talk about Selena's ex, we will always be reminded of Justin Bieber. Fans can already expect that the song would throw major shade at the "What Do You Mean?" hitmaker. Moreover, the former couple's infamous Instagram feud last year fuels the speculations about the upcoming diss track. At that time, Selena wrote, "Funny how the ones that cheated multiple times are pointing the finger at the ones that were forgiving."

We can only wait and see. Hopefully the song will come out soon enough. "It will undoubtedly be tweaked but they were really happy with how the songwriting session went and were loving slating their exes," the source added.
