Lady Antebellum delivered a quality performance of their history-making new song 'Just a Kiss' on the Billboard Music Awards tonight.

Smartly dressed in all black, the superstar trio played the mid-tempo ballad with Dave Haywood on piano and a full band behind them. Hillary Scott and Charles Kelly harmonized beautifully, particularly on the song's hook: "Just a kiss on your lips in the moonlight / Just a touch of the fire burning so bright."

The 'Just a Kiss' performance was another highlight in already memorable night for Lady A. Earlier, the group won the Country Song of the Year award for 'Need You Now.'

The Billboard Awards marked the second recent high-profile performance of 'Just a Kiss' for Lady Antebellum. The group also played it earlier this month on 'American Idol.'
