Listen to Selena Gomez on iHeartRadio

Selena Gomez may have escalated her feud with "Royals" singer Lorde to a new level. 

In an interview with "Flaunt" magazine, Selena schooled the 16-year-old New Zealander for calling the lyrics in her song "Come & Get It" anti-feminist.  Selena challenged Lorde's self-proclaimed feminism, saying that the teenager "not supporting other women" isn't helping her cause. 

The pop star added that she's been covering "Royals" on the road for her "Stars Dance" tour, but wasn't "sure if [she's] going to continue that." 

According to "Celebuzz," since the interview, Selena has stopped singing Lorde's song, treating concert-goers to a version of Katy Perry's "Roar" instead. 

Selena's photos for the magazine are making headlines, as she poses in a short black bob wig and some lingerie.
