The long-running rivalry between 50 Cent and Rick Ross is making headlines once again after the G-Unit mogul took aim at Ross' reported album sales on social media.

On July 21, 50 Cent shared an Instagram post mocking the reported commercial performance of Rick Ross' latest album, Set In Stone, sparking fresh debate among hip-hop fans.

50 Cent posted a smiling photo of himself before taking a direct shot at Ross' alleged first-day numbers.

The post quickly went viral, with fans flooding the comments to weigh in on the latest chapter of the rappers' long-running feud.

According to circulating reports, Set In Stone generated approximately 1.38 million Spotify streams during its first day of release.

Based on industry streaming conversion estimates, that figure translates to roughly 1,220 album-equivalent units from Spotify streams alone.

However, official first-week sales combine streaming, digital downloads and physical album purchases, and neither Rick Ross nor his label has confirmed the project's final opening-week numbers.

Many social media users believe 50 Cent's post was retaliation after Rick Ross recently joked about the rapper's former girlfriend and the mother of his son, Sire, during a promotional interview alongside comedian Deon Cole.

The exchange added another layer to one of hip-hop's most famous rivalries, which has stretched across more than a decade.

Despite years of public disagreements, diss tracks and social media trolling, neither 50 Cent nor Rick Ross appears interested in ending the rivalry.
