Following his split from longtime girlfriend Eleanor Calder, Louis Tomlinson was reportedly photographed kissing a mystery girl in Thailand over the weekend.

The couple, who dated for four years after being introduced by Harry Styles back in 2011, recently called it quits due to the One Direction member's hectic schedule.

"Louis and Eleanor split up two weeks ago. They have not announced this as they wanted some privacy during this time," a spokesman for Tomlinson revealed.

"Cracks were showing for a while. It's incredibly tough with the boys being on the road so much," an insider told The Mirror. "They had a month off over Christmas but since then they have been in Australia and the Far East. It put a real strain on the relationship."

Although she reportedly flew 20,000 miles to Sydney, Australia in an attempt to save the relationship, Calder's effort eventually failed.

"But even after Eleanor flew out to visit Louis, they couldn't work through their differences," the insider added. "Weeks later, when they were on opposite sides of the world again, they called it a day."

With that being said, the "Steal My Girl" singer was spotted kissing a brunette in a swimming pool at a five-star hotel in Bangkok.

"They were snogging passionately. I thought it was Eleanor until she turned around. It looks like he got carried away partying," an eyewitness told The Sun.

The chick in question may be the same "beach babe" who starred in the music video for 1D's 2011 single "What Makes You Beautiful."

"Did u hear louis was kissing the girl from the wmub music video?" a fan tweeted, according to MTV UK. Meanwhile, another added: "Louis Tomlinson's New Girlfriend Was In The 'What Makes You Beautiful' Music Video."
