PATTAYA, Thailand (February 14, 2013)--For the second time in three years, a Thai couple has set a record for the longest kiss, locking lips for 58 hours, 35 minutes and 58 seconds in a Valentine's Day "kissathon."

Ekkachai and Laksana Tiranarat from Bangkok emerged victorious Thursday in what organizers said was the longest recorded smooch in history.

Officials from Guinness World Records must still verify the milestone.

The pair, who also won the annual contest in 2011, received a $3,300 cash prize and two diamond rings.

The event began Tuesday with nine couples.

The contestants were not allowed to sit, rest or sleep.

They also had to go to the bathroom together with their lips locked.

Last year's record, set by two Thai men, was about 50½ hours.
