WATCH: Jason Aldean Sings a Luke Bryan Song to Luke Bryan

Country artist Luke Bryan celebrated his 30th career No. 1 song with a party attended by fellow artists such as Jason Aldean. Bryan admitted he never expected to reach this milestone and initially thought he would only have eight to ten hits. The event, held at Brooklyn Bowl in Nashville, featured performances by Aldean and others. Aldean praised Bryan's talent and recalled listening to his record before it became a hit. The two artists posed together for a photo to commemorate the achievement. Bryan is currently on his Farm Tour while Aldean is on his Highway Desperado Tour.
