The now infamous girl goes by the name of Pia Mia, 17, and is said to be 33-year-old West's musical protégé.

West and Pia, born Pia Ajdba Mia Perez, have gotten close while working together on new projects under his GOODMUSIC label. West reportedly is extremely involved in Pia's projects and has faith that "she could be the next Rihanna," one insider revealed to Radar Online.

While he maintains that their relationship is strictly professional and creative, the source added that he's taken their working partnership a step further and made her one of his go-to's for advice when it comes to his own music and business choices. This has a few people, including his fiancée, a little suspicious.

"Kanye's creative team was pretty shocked that he would use a teenager as his confidante," the source said. "And Kim was actually kind of agitated by it, because he doesn't usually want her input on design stuff. She was a little jealous."

The insider, who worked with West on a shoot in Los Angeles, told the site that the Clique rapper may have crossed professional boundaries with the up-and-coming songstress.

 "Kanye called [Pia] and the conversation sounded kind of flirty and romantic. It could be that they are just good friends but it was definitely more than a professional call," they said.

It probably doesn't help that West overlooks Kardashian and reaches out to her younger half-sisters, Kendall and Kylie Jenner, who are actually friends with Pia Mia, for advice instead.

"Kanye sometimes brings Kendall and Kylie along when he hangs out with Pia so he can pick all their brains," the source said. "He wants to tap into the voice of the hip generation, but it's definitely a little weird."

The source added West is hoping Pia can keep his own career alive.

"Kanye thinks she's young, fresh and hip - totally his target audience. He's been consulting her on a lot of his creative projects, including the Kanye x APC collection," the insider said.
