THE BACKSTREET BOYS are starting their own restaurant. They just filed for a trademark for the name “Backstreet Barbecue”. NICK CARTER Tweeted, quote, “When you have two boys from Kentucky and three from Florida, I promise you that it’s gonna be finger licking good.” They’re also looking to start their own tequila brand. Nick says they’re trying to find a partner in Mexico. Don’t laugh . . . there’s money in it. GEORGE CLOONEY and CINDY CRAWFORD’s husband started their Casamigos tequila in 2013 . . . and sold it off last year for $1 BILLION.
