Now I don't know how true this is but Lou got his 28 tattoo sometime in 2015. And apparently 28 is a very special number to him for different reasons. And this may or may not be one of those reasons. Perhaps 28 might just be a Larry number.

I don't know from which era this is from but the way he's fidgeting with his ring finger is screaming that he's used to wearing a ring on it.

This is from 2015 when Drag Me Down came out. Now this could just be a coincidence, but honestly no one holds their ring finger like that unless they're used to wearing a ring on it.

This is another instance from 2015 when the boys were at iHeart Radio for promo. Lou is again playing around with his ring finger.

I don't know which era this is from but that definitely looks like a ring on Lou's finger. Now this could be just photoshop but I'm honestly not sure.

This is from the 2016 Brit Awards and the way he's holding his ring finger again.

This is from an interview in 2019 and he can't stop playing around with his ring finger.

This is another gif from the same day.

This is from 2020 and while it isn't necessarily proof, it's still quite cute how he shows off his "28" tattoo like it's a ring or something.

This is the most recent proof and receipt that we've gotten of Lou wearing a ring. Now it's upto you whether you'd like to believe it or not. But it does seem quite believable to me.

This is everything that I found so far. If you have anything else, please send it to me and I'll add it to this :)

Also from someone who wears rings on a daily basis personally, it’s a habit of mine to play with my rings and twist them around. Now if I ever take them off, I keep playing around with the fingers I had them on without even noticing. It’s just something I do out of habit.

They both seem to be missing something on their fingers.
