Luke Bryan knows people think theres something fishy going on when his eyes are all red on television.

The country singer and American Idol host explained the true cause of his suspicious appearance in an interview earlier this week.

Just so we know if I do interviews and I look like Ive been smoking pot, thats not true. Ive been catching bass, he said laughing in an interview featured on Audacys Totally Private program on Tuesday.

The Drunk On You singer then detailed just how severe his allergy is.

If I touch a bass, my eyes will get red, like, my hands will swell if I have to take the hook out, he said, adding that if he knows hes going fishing, hell take allergy medicine in the morning to get in front of it.

Bryan said that he spent years not knowing the cause of his allergies, explaining that he and his dad figured it was an allergy to something else.

My dad would take me on these fishing trips and you know Im in the back of the boat, like, wheezing, he joked. We just thought it was allergies, like the trees, but its actually touching the bass.

His allergy clearly wont change any of his hobbies, as the Huntin, Fishin and Lovin Every Day recently went on a fishing-focused trip that he wants to go on again.

Ive done an Amazon peacock bass fishing trip. My children know that Ive done it, and they want to go do it, he said on Audacys Rob + Holly show back in January.

Ive still got bucket list stuff and places I want to go and see and travel. The main thing with me is a New Zealand Brown Trout fishing trip, he added.
