It's official: BLAKE SHELTON'S new co-host for the ACMs is LUKE BRYAN. REBA MCCENTIRE, who co-hosted twice with Blake, plus several years on her own, dropped out last summer so she could focus on her sitcom "Malibu Country". The ACMs are April 7th.

A company called Marco Club Connection surveyed close to 250 club owners, DJs and dance instructors in the U.S. . . . and came up with the Top Country Dance Songs of 2012. LITTLE BIG TOWN'S "Pontoon" was the top choice . . . ERIC CHURCH'S "Springsteen" came in second . . . while KIP MOORE'S "Somethin' 'Bout A Truck" was third.

BRANTLEY GILBERT has moved into JANA KRAMER'S new house . . . but she IS making him pay. She says, quote, "I actually bought the house, and he is living with me, yes. He's paying his little monthly rent." Brantley is also paying in other ways . . . by spoiling her with stupid gifts. She says, quote, "I am really happy. I cannot stop smiling around him. He surprises me with gifts 'just because.'"
