Tunechi’s eldest som Dwayne Jr turned 5 this week – and Lil Wayne wanted to make the day special. So he invited family and friends to a COSTUME PARTY. Lil man has been kind of obsessed with the Flintstones lately, so Wayne got the whole family dressed up as the cartoon family. And Tunechi wasn’t TOO COOL to participate either . . . he put on a FRED FLINTSTONE costume.
