G Herbo’s New Teeth Give Him Confidence, Announces ‘Best Rapper Alive’ Album

G Herbo is feeling on top of his game — he’s got a new set of pearly whites in his mouth, which he plans to use to stunt on his rap peers with a ballsy new album title that’s bound to get challenged!!!

The Chicago-born rapper was all smiles when we caught up with him Wednesday at LAX … thanks, in part, to recently fitted veneers, which prompted a shoutout to “Da Smile Boss” — his dentist back in Chi-town.

Herbo says the dental work’s given him newfound confidence and mental toughness — and advises anyone feeling self-conscious about their mouth to invest in themselves and get the work done.

Herbo had another big, non-dental, revelation for TMZ Hip Hop … he’s standing on business, and naming his upcoming project “Best Rapper Alive.”

A bold proclamation, for sure, and one that could build anticipation for the project — and maybe that’s the point.
