Jason Aldean and Brittany Kerr are definitely in the honeymoon phase.

The newlyweds hit the red carpet for the iHeartRadio Music Awards at the Shrine Auditorium in Los Angeles Sunday, making their first public appearance as husband and wife. Kerr, who wore a strapless black dress with a slicked-back ponytail, kissed the country star as they posed for photos. The two married last weekend in Playa del Carmen, Mexico.

Later in the evening, Aldean won the Country Song of the Year award for his song “Burnin’ It Down.”
