CHONBURI, Thailand (CNN) - Just in time for Valentine's Day, nine couples in Thailand are puckering up for the "World's Longest Continuous Kiss" competition.
They are hoping to break the Guinness World Record for the longest kiss.
The record-holding Thai couple won last year by staying lip-locked for 50 hours, 25 minutes and one second.
The couple hopes to smooch a little longer this year.
The winning couple will get money, a diamond ring and recognition in the record book.
