The pair cuddled at the Lipstick Lounge Tuesday night after hitting Whiskey Kitchen, another city hotspot, earlier in the evening. They were part of a group that included country singer Holly Williams.
"They were very affectionate, just hanging out at the table," says an observer of Hough and Followill, the bassist for Nashville-based band. "They stayed for about an hour and enjoyed karaoke. None of them sang, but they just hung with their group. Only a few people noticed she was even there. They didn't make a spectacle of it."
It's the second time Hough, 21, and Followill, 23, were seen out on the town together recently. On Nov. 23 they reportedly hung out at Whiskey Kitchen with Williams and her husband, drummer Chris Coleman.
A rep for Kings of Leon says: "They are friends and have been hanging."
Earlier this month, Followill's brother Nathan, the drummer for the band, married singer Jessie Baylin in Brentwood, Tenn.
