Happy Birthday Adam Levine! Blake Shelton's bringing the tequila

blake-shelton-adam-levine.jpgIt's going to be a fun night for Adam Levine of Maroon 5, considering Blake Shelton is shopping for him.

The two singers are coaches in NBC's upcoming "The Voice" and Friday (March 18) is Levine's 32nd birthday.

"I'm in a car in L.A. driving to my liquor store, driving to get a birthday present for Adam," Shelton tells Zap2it. "I said I do want to get you something and before I could finish, he said, 'I like tequila.' I am going to get him the cheapest one I can find."

He's also considering a tequila lollipop with a worm inside.
