Drake & Rihanna 'fight,' how did Drizzy win RiRi back (again)? Chris Brown's ex 'wants more boyfriend attention,' vents anger on Instagram?

Drake and Rihanna make a great couple - when Drizzy doesn't put work first, that is...

On Thursday (May 1), RiRi was named "Artist of the Year" at the iHeartMusic Awards. Drizzy was not there to celebrate his girlfriend's big-win, although he was supposed to attend. And rumors suggest that the "Pour It Up" songstress was NOT happy about that.

Rihanna's Instagram is mysteriously unavailable at-the-moment, but following the event she posted some very heated messages on Instagram. One photo was captioned, "I f*ck with you because I saw something different.. Don't start acting the same." Is this a direct blow at Drake?

A HollywoodLife.com insider explains that music is the rapper's top priority right now - even over his relationship with RiRi.

"She misses him entirely. That's all and she wants him to drop everything to constantly be with her."

But Drizzy's trying! "He seriously would if he could," the source continues. "He's just grinding right now on some serious business. 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."

But this doesn't mean they're breaking up.

"Everything is cool though and there's nothing but love between them and all is still 100 [per cent] where he's concerned."

And how does Drizzy work things out? Even when they're not physically together, Drake's constantly calling and sending cute messages.

"He sends texts, he's staying in constant communication," another insider reveals. "He knows she wants that face time, [and] he's got to handle that. There's only a small window to seize all the offers and checks coming his way and right now, he's taking advantage of that... All he's asking is for his babe to understand that and everything will be all gravy."

Do Mstars fans think RiRi and Drizzy will make it in the long-run?
