It seems trouble is brewing in Rihanna and Drake's love paradise. Drake was absent from iHeart music award function where Rihanna accepted her artist of the year award and this has apparently led to feud between the couple. After the conclusion of iHeart Music Award function RiRi posted two angry photos on her Instagram account thus adding fuel to the fire.

RiRi captioned her photo of May 2 on Instagram as as "I saw something different. Don't start acting the same."

Reporteldy, the reason for the couple's latest blow up has more to do with the professional commitements of the rapper. The sources have revealed to Hollywoodlife, "She misses him entirely. That's all and she wants him to drop everything to constantly be with her"

The reports have further suggested that Drake takes his bussiness very seriously and it is of prime importance to him- so much so that everything else comes after that. However, it does not mean that he does not want to spend time with his alleged girlfriend Rihanna.

"He seriously would if he could," the source said, adding, "He's just grinding right now on some serious business."

Moreover, buzz has further suggested that Drake never thought that Rihanna would be so upset with him. Drake and Rihanna have been friends for a long time and the rapper thought they shared a mutual understanding.

"He thought they had an understanding that business is first. He meant that, and that's why he had to cancel some things and not be with her," the source further said.

Does that mean that RiRi and Drake's alleged affair is on it way to hit the rock bottom?

Fans also wonder that now that RiRi is allegedly upset with Drake would she be calling ex-boyfriend Chris Brown to wish him on his birthday?

Chris Brown turns 25 today.
