We had to do a double take when we saw Selena Gomez sitting next to her former arch nemesis Lorde at the American Music Awards last night.

Of course, their one thing in common — Taylor Swift — was right by their side, so perhaps she had something to do with their reconciliation.

Last year, Lorde, 18, dissed Justin Bieber's ex-girlfriend when her single, "Come And Get It," hit the airwaves.

“I’m a feminist and the theme of her song is, ‘When you’re ready, come and get it from me,’” she said in an interview with 'Rolling Stone.' “I’m sick of women being portrayed this way.”

Selena, 22, fought back in an interview with 'Flaunt Magazine,' saying, "That’s not feminism. [Lorde is] not supporting other women. That’s my honest opinion, that’s what I would say to her if I saw her.”

Clearly time has passed and the girls have buried the hatchet. Selena and Lorde accompanied Taylor in the front row of the AMAs last night looking happier than ever.
