The latest stop of the Birdman and Lil Wayne reunion tour was the recording studio, where they posed for a photo with Yo Gotti.
But just because father and son are back on speaking -- and perhaps working -- terms, that doesn't mean their legal problems have been solved.
In fact, TMZ's sources tell them Wayne is still suing his daddy for $51 million and the release of Tha Carter V.
They claim Wayne has just been hanging with Birdman out of sentimentality and still wants his day in court.
