PATTAYA, Thailand - Love is in the air in Thailand.

Couples are locking lips to see who can kiss the longest. Nine couples are getting into the Valentine's Day groove by competing for the world record for the longest, continuous kiss.

The current record is more than 50 hours.

The couples are not allowed to stop kissing at any point - not to eat, or sleep or go to the bathroom.

It may celebrate love, but it's more about endurance than passion or romance.

On top of having the world record, the winning couple will also receive $3,300 in cash, two diamond rings of the same value and a free vacation.
