Nicki Minaj is rumored to be "stunned" and feeling the "sting of betrayal" amid reports longtime friend and label mate Drake is now working with rival Miley Cyrus on penning a diss song about her.

Hollywood Life reports Drake's purported actions are a source of more heartache for the "Anaconda" singer than her raging feud with Cyrus. The two's simmering beef was put on full display during the recent Video Music Awards on MTV when Minaj chastised the event's host for recent comments she made about her that she deemed disrespectful.

Now, Drake is rumored to not only be a part of the equation, but at the center of it.

"[Nicki] feels utterly betrayed and is disappointed that Drake would side with the next girl knowing damn well that Miley said some foul sh*t," said a source. "Nicki's hurt. Drake's blatant disrespect is worse than the stuff Miley said about Nicki."

In recent times, Drake and Nicki's new boyfriend Meek Mill have been publicly feuding, including each recording a diss song about the other.

"It just goes to show Nicki that everything Meek said about Drake, specifically that he doesn't have a backbone and lacks loyalty, is true," said a source. "Now wonder why he first had that many woes in the biz."

Still, other reports are Drake has grown enamored with Miley's spirit and fearlessness, which he's convinced was on full display during her live, on-air blowup with Minaj.

"Other women would have fallen back when Nicki tried to chin check Miley at the show, but what did Miley do? She took two steps forward and was like 'what bi-h?'" said a source. "Drake loves that kind of spirit. That no fear type of woman."
