Nicki Minaj is reportedly upset at Rihanna for breaking fellow Young Money rapper Drake's heart again.

"Drake has been pretty down since Rihanna dumped him," a source revealed to OK! magazine. "She really broke his heart. Nicki wants to call Rihanna out on it. She's very protective of Drake."

The on-and-off "Take Care" duo, who reportedly rekindled their highly publicized romance in February after briefly dating in 2009, split just last month, and now, the Trinidadian emcee is apparently furious and wants to take action against the Barbadian pop star for the way she treated the Toronto rapper.

"Nicki thinks Rihanna needs to step down from her pedestal," the source said.

The infamous feud rumors between the female artists emerged recently when Nicki Minaj and Drake were seen getting intimate with each other and even grinding at this year's Summer Jam, thrown by New York City's Hot 97 hip-hop and R&B radio station.

When the "Pills N Potion" hit maker was done with her performance, she introduced the "Nothing Was the Same" rapper on stage as her surprise guest.

"It's a n*gga in Young Money I don't f*ck with no more: Drake," Nicki Minaj said. "I used to love you, but I don't love you no more."

Drizzy then started performing his hit "Worst Behavior," and a nipple pasty-clad Nicki Minaj soon jumped into his arms and wrapped her legs around him, while he was holding her up.

In addition to the "Moment 4 Life" collaborators' PDA last month, when asked about her ideal man in a recent interview with i-D magazine, Nicki Minaj did not hesitate before naming the "Started From the Bottom" hit maker.

"One day I will run away with Drake and get married," she said. "But right now, it's just a fantasy."
