Liam Payne took to Instagram on Thursday to post a gym selfie, but soon sent his followers into meltdown after they flooded in to express concerns over the star's weight.
Fans commented expressing their worry that Liam looked "too thin" and questioning whether things were going OK with current girlfriend Cheryl.
One follower commented "My love, are u eating? U look so thin..anyway your face is so cute and with Cheryl everything OK?".
Another commented saying "I was so excited for ur selfie but u look so small and thin...Are u eating well? Dont skip ur meal & be healthy pls.".
But the fan panic wasn't just restricted to Instagram. Some fans tweeted the star saying "Your health is important. YOU'RE important", and another saying "Be careful Liam don't work to much you already look really thin u are perfect just the way you are😩Look after yourself ❤️".
Liam spoke out to Attitude magazinne last year about his days when he sported a fuller figure.
He said: "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 bag stage. And for that time in my lie, that was perfect for me. That's what I wanted to do and so I enjoyed myself".
And although Liam and Cheryl seem like their loving life together, we do hope that Liam isn't pushing himself too hard.
