Selena Gomez's new music inspired by Justin Bieber

SELENA Gomez's new music was inspired by Justin Bieber.

According to her vocal coach Stevie Mackey, the brunette beauty - who was in an on-off relationship with the 'Boyfriend' hitmaker until October 2014 - references her failed romance with the 21-year-old star in her latest offering.

He said: "She doesn't mention him directly. But one could deduce that she is [singing about him]. Most artists sing about their present or past relationships in their music. Selena's no different."

Stevie also addressed speculation that the 'Come & Get It' singer's hotly-anticipated new track will be titled 'Unbothered' after she reposted a photo of herself reclining on a kitchen counter with the caption "Unbothered!!!!" yesterday (10.06.15).

Stevie, who had previously uploaded the picture onto his own account, explained to "That's not the title of her song. She just looked content and unbothered, so I put that on my Instagram. I was just showing her love."

Selena, 22, also hinted she is working on new music with songwriters Justin Tranter and Julia Michaels after adding a photograph of herself sitting in between the pair on a sofa.

She captioned the image: "From LA, Mexico back to LA. This is a magical team.... #SOON. (sic)"
