Eric Bellinger just dropped big news … and of course he celebrated it by turning up at the “TMZ After Dark” tour, Monster Energy in hand, keeping the party fully charged!

Check this out … the singer/songwriter was riding high on our party bus Saturday night, with extra reason to pop bottles — he just inked a deal with Capitol Records!!! 🥳

Eric’s big career move had the whole crowd lit, dancing like crazy … the bus was packed shoulder to shoulder, and even folks in the next rides over were trying to catch the vibe.
