Here at Guinness World Records HQ we're getting swept up in the romantic spirit of Valentines Day.
And we're not the only ones - in Thailand, 14 lip-locked couples have taken part in a contest for the longest kiss.
Among the contestants was an elderly couple with the surname Yomjinda, aged 74 and 72 years old.
The long-time lovers attended as part of the celebrations for their 50 th wedding anniversary.
The nine couples were trying to surpass the world record of 50 hours and 25 minutes, set by Nonthawat Charoenkaesornsin and Thanakorn Sitthiamthong last year- who returned to try and beat their own personal best.
While we await confirmation to see if any of the couples beat that time, here are ten of the most lovey-dovey world records that are sure to make you swoon.
Oldest love poem
Archaeologists have dated a love poem written on a clay tablet to the time of the Sumerians, who invented writing ca. 3500 bc. It was given the rather unromantic name of "Istanbul #2461" and is thought to have been recited by a bride of the Sumerian king Shu-Sin, who ruled between 2037 and 2029 bc. It begins: Bridegroom, dear to my heart, Goodly is your beauty, honeysweet, Lion, dear to my heart, Goodly is your beauty, honeysweet.
Highest box office film gross for a romance film

On 1 February 2002, François Fernandez (France, b. 17 April 1906) and Berthe Andrée "Madeleine" Francineau (France, b. 15 July 1907) exchanged marriage vows at the rest home Le Foyer du Romarin, Clapiers, France, at the age of 96 years 290 days and 94 years 201 days, respectively. Their aggregate age at the time of the ceremony totalled 191 years 126 days.

Earliest box of Valentine's Day chocolates
Richard Cadbury (UK), the eldest son of John Cadbury, founder of the world famous company, created the first known heart-shaped box of chocolates for Valentine's Day 1868. He was a pioneer in chocolate box design and often used his own paintings to make the lids of the boxes more appealing.
Longest screen kiss in a TV show
The longest screen kiss in a TV show is 3 minutes 22 seconds and was achieved by Sean Lowe and Lesley Murphy (both USA) at the Guinness World Records Museum in Hollywood, California, USA, as part of an episode of ABC's "The Bachelor," filmed on 30 September 2012.
The longest hug lasted 24 hr 33 min and was achieved by Ron O'Neil and Theresa Kerr (both Canada) at Centennail Beach in Barrie, Ontario, Canada, from 12 to 13 June 2010.
The attempt was a fundraising effort for the Juvenile Diabetes Research Foundation.
