Harry Styles reportedly isn't best pleased with Louis Tomlinson's recent behaviour.
It all kicked off on Twitter earlier this week when Louis seemingly got irritated by a photo uploaded by producer Naughty Boy. The shot was of Naughty Boy and ex-One Direction star Zayn Malik, and the pair are currently working together.
Louis and Naughty Boy continued their public spat on the social networking site, which resulted in Zayn getting involved. Now it seems Harry isn't happy with what went down.
"Harry is very aware of 1D’s reputation and doesn’t like getting into any public scrapes, especially with other members of the band," a source revealed to British newspaper The Sun.
“It’s fair to say his relationship with Louis has been strained for some time and the last couple of weeks hasn’t helped matters.”
Zayn announced his decision to quit the band in March, upsetting One Direction fans all around the world. The rest of the group, Harry, Louis, Liam Payne and Niall Horan, have vowed to carry on stronger than ever, but after the Twitter argument it appears tensions are high.
However, a music insider says all is OK with the boyband.
"Harry and Louis are working together in the studio in Los Angeles on 1D’s next album. They’re fine," the source said.
The boys have been pretty quiet on Twitter since the Louis and Zayn fight, but Louis has shared a post thanking all their fans.
"Our fans support really has been a different class ! Huge love to you guys !! (sic)," he gushed.
