Paul Wall: My New Pup's Getting Grillz

Paul Wall's next trip to the jewelry store won't be for himself ... it'll be for his brand new English bulldog puppy.

Paul tells TMZ he jumped at the opportunity to adopt the 12-week-old pooch when his friend's dog had a litter. He says his kids, Noelle and William, had been pestering him for a dog, and he really wanted an English bulldog.

The rapper says the kids named the little guy, Champ. And who knew this was a thing ... but Paul says once the pup's teeth grow in, he's going to have him fitted for custom grillz.

Champ's already putting in work, modeling swag from Paul's companies.

Damn cute spokesman!
