I dunno about TV star or musician, but I'd pick Will Smith, he's just fucking awesome and seems capable of surviving a zombie apocalypse.
As for pet, I'd probably pick an african elephant. If you're riding on one of those things, you're pretty much untouchable, plus it can stomp through pretty much anything, and with all the stuff you'd be able to loot, you could make a suit of armor for it too. War elephant go!
If fantasy is allowed, I'm going to have me a fucking dragon.
Will Smith has an educated background, went to catholic school, and was class clown. While I love his movies, he's not a tough person irl.
