One Direction fans are known for their fervor, so it's no surprise that when Liam Payne posted a selfie where his face looks pretty thin, legions of 1D supporters have flooded the Internet with their fear and concern that the singer is "too skinny."

On June 23, Liam posted an up close and personal snap of his face on Instagram with the caption, "Time for gym #hashtag."

Soon throngs of Instagram followers flocked to the post to share their alarm at his somewhat gaunt countenance. Some fans have also suggested that he's broken up with girlfriend Cheryl -- and the weight loss is a result of a broken heart.

Liam is no stranger to issues with his body and people commenting on it. Last year, the singer spoke out about his physical insecurities, explaining that during a rough time in his life he gained weight and drank too much.

The 22-year-old told Attitude magazine, "I started drinking a lot and I began to get a bit tubbier. In fact, because of that I was getting fat jibes all the time, which hurt me... I'm not afraid to say I went through a pretty bad stage. And for that time in my life, that was perfect for me." The boybander added, "That's what I wanted to do and so I enjoyed myself."

However, he's been hitting the gym since his "tubbier" days, posting photos of his taut tum on Instagram.

Interestingly enough, his ab photo from four months ago didn't cause alarm -- only the recent selfie of his face started mass Internet hysteria from his die-hard fans.

Meanwhile, Liam's girlfriend, former Girls Aloud singer Cheryl (formerly Cheryl Cole), has faced similar concerns about her frail appearance in the past.

Perhaps the couple can seek solace from the comments together?

Last year, the Internet erupted with concern after the Brit appeared at "X-Factor UK" auditions in Manchester, England looking scary skinny.

After being plagued by comments about her weight, Cheryl took to Twitter to rant about the digs, writing, "I am so sick and tired of it being ok to call somebody too thin or a 'bag of bones. I would never dream of calling somebody too fat and that they should maybe cut down on their food intake?"

The 32-year-old also explained she was grieving over the loss of her former father-in-law. "You have no idea what I have been through. Just loosing my father in law v recently and everything that comes with that [sic]. Not that I am or should justify myself to anyone," wrote Chezza.

The singer continued, "I'm so f sick of people thinking it's ok to be mean or body shame anyone. And it's woman on woman. Have some respect and maybe think there may be reasons why before opening your mouth please."

Well, whatever is going on with Liam (and Cheryl) -- we hope they're doing okay …
