Given their decades of history and success, it was hard to fathom a fallout between Birdman and Lil Wayne. They were a musical tandem to be reckoned with -- father and son; label boss and star rapper.

And then Wayne, on Twitter, in December 2014, voiced his displeasure with Birdman and Cash Money, saying he wanted "nothing to do with them," and that Tha Carter V was being held hostage. From there, the relationship only seemed to further crumble. Weezy sued for $51 million. He addressed the issue in songs. There was reportedly an incident involving drink-throwing between the two -- or their camps -- at a nightclub.

For months, there haven't been many (any?) signs of reconciliation between the two. But on Thursday, Birdman may have offered one, when he posted a throwback picture of himself and Tunechi with the caption, "YMCMBeast #BLATT."

Of course, we can't actually read too much into this. It could be Birdman trolling. It could just be him caught in a moment of nostalgia. It could mean nothing for the promise of a positive future between Bird and Wayne.

But I hope it does. I really do. Both because I'm ready to hear Tha Carter V, and because these dudes have such a storied history together, it would be unfair to their past and collective legacy to see it end like this.

Below, check out 50 Cent's take on the tiff between the two, from when MTV News spoke with him earlier this year.
