The former One Direction heartthrob was snapped leaving London's Cirque le Soir nightclub with his girlfriend Danielle Campbell, but his appearance has supporters super worried!!
Directioners took to Twitter, speculating that the 24-year-old looked 'unhealthy' and 'exhausted' (that or he could just be drunk...)
Some 1D followers even got the hashtag #LouisTakeCareOfYourself trending, and began comparing photos of the artist's fuller frame to the new snaps!!
My heart breaks when i see how tired and thin he looks. I wish i could hug him and make everything better... #LouisTakeCareOfYourself— Charry (@smilexharryx) August 25, 2016
