Why Blake Shelton Wants Adam Levine to Start Drinking

In the August issue of Men's Journal, Blake Shelton explained why Maroon 5's Adam Levine — Shelton's fellow coach on NBC's "The Voice" and real-life buddy — should start boozing it up.

Shelton himself prefers vodka with Diet Cherry 7Up, but substitutes club soda and stevia for the soda these days. (His wife, country singer Miranda Lambert, "says it's healthier," he explains.)
