Why did Louis Tomlinson delete this loving Twitter message to Harry Styles? 'Larry Stylinson' gay fan fiction rumors erupt! [PHOTO]

Back in 2011, One Direction's Louis Tomlinson posted a tweet that had a loving message to his bandmate Harry Styles. This post was deleted earlier this week, resulting in the Internet trying to come up with reasons why he would erase such a nice message from Twitter. Some theories are even bordering on the fan fiction realm.

In this message, Louis wrote: "Always in my heart @Harry_Styles. Yours sincerely, Louis."

Here is a photo of the tweet in question:

So why would Louis delete this nice tweet 3 years after posting it? Some theories point to the overwhelming fan fiction craze known as "Harry Stylinson," which pairs these two boy band members romantically. Apparently it has become way too much for Louis, so he went back into his Twitter archive to make sure nothing could support this strange claim.

"Me and Harry are best friends. People look into our every move - it is actually affecting the way me and Harry are in public," said Tomlinson last year. "We want to joke around, but there seems to be a different rumor every time we do anything. I act the same way with Harry as I do any of the other boys."
